Mine went about 300 miles in 4 years so tires sat alot too
I don't notice any problem
Have to get the wheels unlocked to even get them off
No key
LOL

Glad its not the front end
the Volvos was a good hit to the $pocket

CamelotShadow · #**977** 10-25-2007, 10:14 PM

Keyes called
Maganese came in
So I did want to take the benz out

Starts up same cold in a flash
1000rpm then increases & comes down
so its the same there
No Problem

Thinking I need to keep a full tank of gas
but didn't want to dilute the techron
I have half tank
so figured if I get another small bottle for 12 gals
I should be able to fill the tank & have a suitable concentration.

So went to Pep Boys this time got the small bottle for $8
Actually the corner Chevron was a decent price

Also picked up CRC throttle body & intake spray
thats ok for coated throttles
just in case I feel like doing that

Started up with a few second crank assisted with some pedal
On restart in park its about 750
then drops to 600 or lower in drive
but its steady quiet & strong.

I almost couldn;t tell it was running at one time
thought it stalled

Then we went over to Keyes got the paint & a bulb for the tail light
Got the first guy & he gave me a discount
so I saved $4

2nd restart I let go too fast didn't take & stalled
got it ok after that

Just have to get the feel for it
but it is much less cranking than it was
I can handle this so it has gotten better but is not cured or as good as the cold start.

Drove to Trader Joes for rations
3rd restart ok
same few second cranking & assist w pedal
but nothing like the crank city it was...

Drives smooth & responsive
May seem not aspowerful to me
but maybe I;m getting used to it

Decided to get brave on drive home even though idle was 600 or less

Turned on the AC as it was about 90 F today
Car ran about 90C today...same w AC
thats good!!!

AC blew ice cold amost immediately
Closed the windows
Yeah!

no more smog
Volvos AC needs a recharge

Idle did go lower w AC
probably real close to 500 if tack is accurate
thats a lil close
but it ran steady & was ok at ligfhts.

Might want to increase the idle a hair

Thats about it

So we had a nice outing...
Don't really know if I can honestly say it runs any better with the new plugs & wires
They may have been ok

Can new plugs wires or accululator lower idle?
Maybe the vac switch?
He said that was for timing

Have to add the tech tomorrow & fill it up
Good to have a full tank just in case
never know what could happen to gas supply

With cars that have electronic fuel injection like yours, it is not recommended to pump the gas pedal when you start them up. that is a hard concept to accept for those of us who grew up driving cars that had carburetors.

Sounds like it is running well. 750 rpm at idle is a lot better.

My personal opinion is that buying bottles of Techron is a waste of money, if the car is run with the proper fuel.

Just use Chevron Supreme fuel, it has Techron already in it, and cleans the injectors as you go. I used it for 70,000 miles on mine with no problems.
(Though I did replace the injectors when the timing chain was replaced, at approximately 100,000 miles - - - preventative maintenance.)

I'm running the concetrate as it sat for atleast 4 years with av of 50 miles per year so it might have some deposits from that.

Thats inpark 750
may be below 600 in drive
but it is running
the idle went down with the repairs
not sure what did that?

When cold it starts unassisted

I'll have to try to see how much I have to crank to get it to start wo pedal assist when hot or warm.

I have a earlier K jet or KEjet
not sure
but its sort of a mechanical electronic fuel injection.

The manual says if it doesn't start hot/warm to depress accelerator
so it must have been a issue w these cars.

My Volvo was my first electronic fuel injection
& it starts hot fine
Don't have to use pedal but its a 88 not 83

CS,
Glad it is starting better now. Sometimes you will find you do have to hit the accelerator a bit when starting...the car is not new and it does need a touch of fuel sometimes, most eventually do. Does sound like it is better. The new plugs and wires are what is smoothingout the idle and making it at one time seem like it had stalled. They are doing their job. Better idle and smoother running engine.
Jim is right about the techron. I still use it every so often, but after you run through this new bottle the engine and injectors should be nice and clean and you can probably swith to just the Chevron fule with the Tech in it. Then is you feel like it once every so often, buy a bottle. I usually do it every couple of oil changes. Cant hurt and cleaninjectors is the name of the game. Clean equals better spray pattern with equals better running engine and better gas milage.
With putting few miles on the car you could do it less but it really cant hurt much doing it more often. Just might not have anything to help. Still cost the same if you doit at a regualr interval.
I would say you can stop fussing with your idle and your engine situation for a time and focus on the wheel lock key. It could become much more important at anytime if you have a tire problem on the road.
Good luck.

HI CH
Hey we have the same initials

I bought the smaller bottle as I want to fillup the tank
I'm on half so I ran about 1/4 tank of the stuff
I don't want to run the tank down.
If I get a half tank to fill it up iit will dilute in half
So I figured I'd treat the other half tank when I fill up
it should be about 12 gal & I'll run it for another half tank before I gas up.
Least then I will have run 3/4 tank of the stuff before diluting...
Do you see what I mean

Have to find aplace for the wheel lock
nothing I know around here.

I don't know what the plugs looked like
but the cap according to Enrique was not bad
so it would seem the engine was runnning wo too much problem
but its good to start fresh with least wires
I think they were old
Can't tell about plugs
they could be 6 years old with 300 miles on them...
No way to know wo taking them out
so might as well put new ones in
They were about $15 for the plugs
no biggie

I would have liked to see cyl 8 plug
founf the most carbon on cap there
something with that plug or maybe even wire

AC works great
ooooh
almost worth getting the car for that
I got a nice running car w AC
for not too much $
What more can you ask for?

Couldn't tell if it was smoke today or exhaust
but the car is heavy on the exhaust...
just add this air & driving could get you a headache

I'm happy
It feel good to get the ole benz back on the road

OOOH oil pressure at 90C is about 1 1/2 2 at idle at lights
but then pins the 3 upon acceleration
guess thats normal for a hi mile engine.

RPM;s seemed different speed
Now at 35 or so it was 1500
think it was much lower last time

No big deal
just trying to figure it

I can also hear the tranny whine down to stop now
never used to notice it

I know
I hear too much
I think too much
but I never talk on the phone & drive...

Jim B. · #**982** 10-26-2007, 12:50 AM

Nice car.

CamelotShadow · #**983** 10-26-2007, 01:28 AM

Hey saw that car last week
I remember it was a DR's car...

US AC

I like the color better on the coupe
My car just looks sexy

I have noticed a few 126 coupes on the road
& none look as sleek n sexy as mine.

Heres a pic from curbstoner at idle
can see
1000 rpm
oil press 3 bar
note he hides the temp???

I got the car home in 3 miles
Cleared 170 today so I've used it about 150 miles

Hey thats more in 2 months than its done in 3 years

BENZ-LGB · #**984** 10-26-2007, 02:02 AM

...for a mini GTG at Enrique's. Just let me know which Saturday, because I have to make arrangements for my wife to drive my son to the airport where he does volunteer work every Saturday.

Weekdays are bad for the next couple of months because I have a few trials coming up. So Saturday is perfect.

I second Camelot's suggestion regarding a location to stay. Tarzana is boring, Studio City is far more interesting....not as interesting as SanFran though.

Luch at a nearby Cuban restaurant is always good.

so, I am in like Flynt!

mercmad6.3 · #**985** 10-26-2007, 04:26 AM

Evening From Brissy!.
Your injection isn't electronic,it's mechanical and it's called a 'Kjet'
You say the exhaust is "heavy' .Do you mean it smells strongly of exhuast fumes?.
The CO needs to leaned out by the sound of things. I am nearly finished this AMG car here and the CO was adjusted from it's 6.0 (!!!

!!!) to a more legal 1.5 C.O.
it now starts instantly hot or cold.
The AMG specs call for idle at 800RPM. but because it has the same dodgy heat controlled air slide like yours it will only in drive at just over 500RPM.
With the airslide you have,get the car hot,and with it in park and the air off,turn the idle so it's 1000 RPM. It will then idle at more happy 650 RPM in drive and aircon on.
The idle control is that large white plastic screw next to the airslide.Anticlock wise is increase idle speed and vice-versa.
Normally ,with the proper electronic air slide you will idle at that speed constantly. Some sedans were set to idle at 500 RPM .
These coupes were designed to have the automatic idle control , so when the car is hot the electronic idle control compensates for this and gives an extra shot of air to start the engine.It should start within half a engine revolution

Now for something I take issue with your mechanic about....that green and white plastic thing on the intake?
It's called an "orifice" because it has special hole inside which is designed to restrict vacuum at idle and at speed( full throttle) it's bypassed to provide vacuum for the distributor.
Your's is on back to front.
White side faces the intake manifold.
If Your car gives the impression that it doesn't have much power,that's because in light throttle take offs ,it's in second gear. Half throttle and full throttle take offs should give you 1st gear .If not,the transmission throttle position cable needs adjusting.

That photo definately shows a car that had a high idle issue at the time.
I wonder why the temp gauge is hidden. Good catch, but then, he could have snapped the photo when the engine was ice cold to conceal overheating issue showing up on the heat gauge.

Ah , curbstoners. A lot of them are Russians, I heard who fix up junkers and sell them. They no a lot of tricks. Maybe living in Russian taught them that?

AGREED the coupes look sexier than anything around, in any color. That is why most buyers like them. The sedans and diesels look ambassadorial, stately, formal, dignified.

I am hoping to firm a date up for the gtg at MR MB by asking Paul S and Curtis if they would be interested. Then call up Enrique and see if he can take me car in - and ask him if he would mind, if all of us showed up for a gab fest and car show on 11/3. If he says yes, then, on with the show.

Being on call, or even being selected for, Jury duty, won't affect affect you.
Only keep dialing the hotline, the Courts only work M-F 9-5, and if all the cases settle you won't be called. That used to be part of my job in the Courts being involved with all that. (San Francisco when I was there)

Your car looks beautiful. Still I would welcome the opportunity to look at it up close. Believe me, it could hold its own against any other SEC, for looks, and surpass most other cars on the road. Dont forget it was the best car Mercedes Benz sold, in '83, and back then Mercedes was the best of almost ALL cars. What other 1983 car could make that claim?

I bought a can of NEV R DULL, the impregnated wadding, today. That stuff cleans aluminum REALLY well. Especially the air cleaner on the SC, which is what I will try on mine. I gave mine away about 5 years ago, when a Norwegian guy I had met on vacation, by arrangement, who owned a SEC, visited SF and I met him there with his business friends at the Norwegian consulate.

If I remember to throw it in the car, and go to Mr MB, and you show up, for a mini gtg, some of the stuff to rub on the air cleaner and try it out.

If not remind me, and I could leave some with Enrique in a bag for you to pick up the next time you are in there.

Thank you Ernesto, CS and Charlie for the valuable information about phones, hotels, and affixing the ashtray wood.

I am hoping that Enrique will be able to fit my car in at the end of next week.
If so, and if the new wheels are on the car, I will point it south - Maybe on Tursday night?

Yah, I will check the oil before I set out.

feet, spits on ground>

It's not a high idle issue ,because as I pointed out ,this car has the wrong idle control airslide fitted.
As such it needs the idle to be set high to compensate for the aircon when it's turned on.Too low and it won't idle .
High heat would have lowered the oil pressure,even at 1000RPM. The guages look good to me,3 bar oil pressure,high vacuum AND 1000 rpm idle.

I'm good for November the 3rd.

I could be there around 10:00 a.m. That would allow Enrique to get the morning rush out of the way. We could hang out and shoot the bull for an hour or so, and then walk to the Cuban restaurant next door.

Hi Brissy,

Glad you got the AMG running so well
How'd you fix the hot start?

The new acululator has made it better but maybe something else can help?

Thanks for everything

The white or in my case yellow side faces the intake
Is this wrong?

I asked him to check the yellow/green orifice.
He knew about blowing in it
I asked him if he checked it & he said it was on right
So there was meeting of the minds

I cn blow in it
you suspect air will come out the green end or white?

Actally the yellow side faces the intake so wouldn't it be right?
green faces outside the engine
yellow faces toward the back fuel dist

I mmentioned the airslide only after he was done
I didn;'t mention it as I didn't want him to change the idle
It was ok
about 1000/900 in park
then 650 in drive

Its running at lower idle now
not sure if he adjusted it down

He said if idle was too low that I could raise it
I'm not sure if he meant to raise the screw on the airslide
or as you say the idle white thing thats more yellow from age on my car.

The larger plastic screw next to sirslide has 2 holes on top
its not really for a screwdriver. I suppose I could increase the idle a hair to get it a lil higher.

When its warm on restarts
I;d say in driveits running 600 or maybe even lower wo AC
Car specs are 600 to 750

How do you lean it out?
