RE: idle problems on 380 sec

Sorry if I sounded rude on that last post, we need some kind of w126 high idle problem forum where we just talk about that…[xx(]

Review the list and eliminate each possible problem. Item 1. (one) is the most common problem to the least occurring problem.

RE: idle problems on 380 sec

yea ive had the problem for a while. you would think there would be a pattern but it usually happened at the randomest times. the trick is when its "idleing" or reving you have to put it into park at like a stop light and just rev it as hard as you can for a few times and put it back into drive. that usually works for me. you could probably get it fixed but its always too expensive. this is something that you just gotta live with

I have a similar problem with my 1980 280SE (gray market) car. It idles high (2K RPM) in winter and lower in teh summer; when A/C is turned on, idles even lower at the point where engine stalls. It is burning so rich, and exhaust fumes enter car when is not in motion. I appreciate any recomendations.

Here’s the list if things to look for first for high idle, common to all CIS cars:

1. Idle control valve
2. Idle control unit
3. OVP relay
4. Throttle position switch
5. Worn injectors
6. Broken/brittle/missing/disconnected vacuum hose(s)

I’m not sure of the location of the ICV or number 4 on the M110 but number 2 should be under the dash driver’s side and three is in the fuse box.

I would add to the list :

- worn injector seals
- worn inlet manifold seals
- incorrect air metering plate adjustment
