Tenterfeild is a nice little town, and the history between Glen innes is really interesting too,the Gay Singer and one time husband of Liza Minelli ,the late Peter Allen came from there.It was also where Australia become a sovreign Nation instead of a collection of seperate colonies.
Glen Innes was the home of several Famous Australian Authors,Including Ruth Parks whose husbands works included the Peter Finch Movie ." The Shiralee" .

Now to Business.
These cars ALL came with the electronic idle control.
This one I am working on now has been bodged like yours.
WOnder why both are messed up same way?

The Warm up regulator should be connected so that the Front lower port is connected to the Throttle switch on the throttle body.
The correct port is on the (your) passenger side of the throttle (it's down under the large airflow meter thing) .

:confused: Have to check for that!

If you shine a light down there you will see a white plasti device with three hoses leading off. the top hose is the connection for the front port on the warm up regulator.

The Port on the rear( at the bottom) of the WUR is connected to the left hand thermo switch device directly behind the WUR. ( you should have two of those,left and right) .
This must have a large black plastic hose with a rubber tee which then connects to a port half way along the intake manifold
.:D Yep got that!

On top of the WUR is a hose which connects to the large black hoses feeding into the intake airmeter from the Airslide device.
:D That's right!

Now...on the opposite of the throttle body ( your drivers side) are two ports .The top port must be connected to the EGR valve.thats the big device on the drivers side exhaust manifold.
:confused: need to check

The lower port is connected to the Vacuum switch,thats the metal device mounted to the left hand fender .It has one plastic line and one electrical leading into it. :confused: have to check



The other plastic leads come from the white plastic device of the passenger side of the throttle body.On the underside of the switch where you cannot see them ( ) are two ports.
The lower one ,connects to a 4 port rubber connector. :eek: there is one leg of the quad tha I don't know where its from...

The upper connects to line running from the engine to the point on the firewall where it connects to a reservoir.This a long line,around 4 feet in length
.:confused:

The 4 port connector is connected to the intake by the green/white one way valve.the green side is faced towards the manifold.
:( mine haS yellow toward intake

one lead from the 4 port connector is to the ditributor.
:D Right

one leads to the left hand switch behind the WUR> :D
yeah when it was not broken
Now its connected to bottom of T that used to also be in the broken TVV

The right hand switch activates the EGR so it's not important that it's connected ( well..not here anyway)

Right hand switch is not broken
has 2 lines on it I couldn;t trace...so thats the EGR?


Hey

thanks!
alot to digest

yeah knw about Leggs Diamond
how could we forget the
Tenterfield Saddler...

Glenn Innes
has sapphires
better hospitals

First thing I have to correct is if the green/lemon vaLVe is a one way valve & should be like yours
then mine is backwards

valve behind wur is OK
goes to left thermo vac switch then to the back side of the intake
I see your hose is off & I see the port in the intake
so thats ok (at least it will be when the tvv thats broken is replaced)

the top wur valve goes to the rubber port off the icv so that ok

I never traced the red hose on the front wur
it goes down can';t see where...

Some are fine
Some I; have to trace

Seems that green yellow one way valve might be backwards unless thats a down under car

We all know things go the opposite direction down under...

LOL

Thanks

Helps me get going iun the right directtion!

Trying here
but don't see some of those ports on the throttle body
inside it?
under it?

My head is swimming

its late
maybe some sleep

just think as mine is a mid year 82
its not matching up with the 9/83 parts book
darn

Anything I am missing

think there is another unattached wire on left drivers side of intake too..

I can't seem to see vac hoses on the throttle body like in the digram

I'll have to takeoff air assembly & see if I can see better now that I have more of an idea for what to look for

Are you sure my yellow green valve is backwards?

If it is guess correcting that should be a good thing

Thanks so much again

pICS OF us 85 500 SEC

THIS HAS THE ELECTRONIC icv BUT HAS A different vacumn setup
see a y hose in there as in my 83 parts cat

also see it has a 50 & 70 TVV
air inject valve is blue


good pics on this site though

He's got WUR on backwards!

its the right way later

Front wur vac connected to a Y vac hose?

Thats somewhat later,yours is an earlier car with vastly different vacuum set up.
It's a pretty simple matter to get the air assembly off,and is in fact a good idea because the black rubber moulding underneath is prone to cracking which can cause idle problems,while there it gives you a good chance to replace any cracked lines etc.
The sensor you circled with the question mark is a engine water heat sensor to tell the injection and electronic idle control that the engine is warmed up.

Hi...
Guess its Monday in Brisbane

I have had the air cleaner assembly off a few times
Its no problem

The rubber under it is ok

I did clean the assembly
was a small amount of soot

I;d like to clean the throttle body
but the right way not even sure how to go about that yet

Been doing research so I can know my way around in that area
& its hard to find 82/ 83 cars
I remember trying to trace those lines most of which you say got to throttle body or throttle switch & they are hidden

Been reading not to use carb cleaner in throttle body as its much too strong... I got it basically for external cleaning
Good thing I didn't us it in there
as there are seals & things & also a protective coating that could be damaged...

Also you should dab a dot of oil on the shaft when clean...?

Thats my fuel dis & air plate sensor pictured above
I really don't see any vac lines hooked into it
Will have to get a better look but since I live in a community garage & really working on cars is not allowed
I wait til weekdays when most people are in work & then I can do it less noticed...

mercmad6.3 10-21-2007 10:11 PM

Sorry,i thought you meant the upper part of the throttle body. once that is off everything becomes clearer.
I understand what you mean aboutr community garages,i'd go nuts if i lived where i wasn't allowed to work on cars.:D
So far you havew nailed down the majority of things that can go break and cause running problems.The biggest single thing you can do with those cars to make them run better is to DRIVE them.
The design of the valves etc ensures that the engine runs better and better the more you use it.
if you want to go ahead and buy a idle control unit and it's electronic box,this guy has them cheap on ebay second hand. I've bought from him before and his prices and Knowledge are very good.

I'll second Redlands-Mercedes-Parts. I have also bought from him, fast and good parts.

CamelotShadow 10-22-2007 01:22 AM

Nice!

Thanks
I bookmarked him

Have to discuss this w my mechanic
So far the setup has been ok
just the cold idle
& the worst part the hard hot starts

I hear you about driving it
I'm looking for places to go

Too bad Malibu self destructed on me

Fires all over LA
Getting to be like Hades over here
