Hello and welcome. There is an idle adjustment screw under the air filter housing. It's on the engine side. You will need a long screw driver to reach it. I think it's a flat bladed screwdriver you need. That's on the M102 2.0l so it should be the same on the 2.3. Stu Edited by stwat, Sat Jul 24, 2010 9:23 pm.

Air leaks in the inlet system can cause high idle problems. .....Oh and welcome to the forum

Hi, If the Idling screw hasn't been touched then I would say it won't be incorrect, as it doesn't usually turn itself out of adjustment I am inclined to agree with Richy 190 E. Check ALL vacuum hoses for splits, condition and also that they are all on correctly. You don't mention whether your high idling is constant or at what revs it idles at. And at what running temperatures. Also have you the Eco Gauge and what that is showing. |
