Different Air Idle Control Valve Effects
 

Discovered I don't have the normal horizontal mounted
ICV with the 2 pin connector

I have a bosch air control valve

I am asuming this is run by vacumn not electric?

Since I am having a hi start idle in park
& a hard hot start problem
I was wondering how this might be affecting my system.

I found a 2 hole electrical connection in that area
Don't know what it was for
but I suspect the orig ICV?

Would this ICV have problems with my car?

It idles fine in drive
but is higher in park.

Also when started a cold engine in park
starts maybe 1200 & slowly goes up to 1500/1600
then comes down to 900/1000 when at operating temp

Still this isn't really affecting anything
as its just a start thing
& the idle is normal 650ish in drive...

Hard to deal with things when I don't know if the different ICV might not just be working in the same way the original would...unless of course this is the original & Euro was different

but what would that connection be doing there?
Anything else in that area it could have been used for?

Just trying to figure this out...

Any ideas would be appreciated...
Thanks

Someone has swapped either the complete engine with a 450!!! or they swapped the idle control system with a 450 intake manifold system.

You might want to look at the engine number!

:confused:

Yikes, Goodness
It was in hands of pne person since 87



Where do you find engine number?
I read siomewhere on left rear?
but havn't seen any



There are numbers on right top valve cover

OOOH well, can't worry bout it now
but I would like to figure it out

Thanks

Looks just like my 85 EURO 500. The euro didn't have the electronic ICV but instead had a heat activated ICV which is what you have. Look on the block just behind the left (Drivers side) head. You should find a number like 117.963 or 117.961 followed by some other numbers which I think is a serial number. The 117.963 is the US version and the 117.961 is the EURO version.
I have a US car with a EURO engine which I converted to the US ICV system and it works well.

Ooooooohhhhhhhh Thank YOU!

Been googling for hours w no luck

Thats promising good news too

I hope its original
but guess they say
it is what it is

Wonder why its not on the dataplate...

anyway only porrf of whats in it is the engine #

Thought it was around there

I'll have to look better

Thanks again!!!!!

:D

I did see a Swedish 82 Euro 500sec
looked like it might have had the electric icv but pic was a bit hard to see
so who knows....

Almost impossible to see
 

On the block behind cylinder on left drivers side head?
Is that right up against rear firewall?
Very tight in there
maybe with a long mirror

Is the cylinder head under gasket of valve cover?
Block is that a more central part.

sorry, still not sure about block or where
but doubt I could see it anywhere even if I knew where it was...

I tried to see
Took some pics
sometimes my camera pics it up

OOOH well
it is whatever it is
I just would prefer original

Thats not entirely correct. I have both Euro and national model engines here,some are electronic idle and only the early 380's were heat controlled idle air slides.on cars equipped with temp units there is also a idle switch over valve activated by the aircon circuit to increase idle by altering the distributor advance.
As on our friends car here i have found the only Euro's to have heat controllecd airslides are ones that have been bodged to rectify a high idle situation. A lot can happen to a car over 23 years.

Hey Brisbane!

My parents live in NSW

Do you mean my hi cold idle?

Also it really is a 82 500 SEC
Who knows
it had to be converted to pass emission when it was imprted
Who knows what they did...


Luckily in drive the idle is where it should be

Still chasing the reasons

Boy I wish I had this car in Australia
except it woudln't like the dirt roads to the farm house...
