My car doesn\'t want to idle!!
I've read posts and done some searches. I still don't know what to do. I have warranty, but I hate to have to take it to my local 5 star dlr for many reasons. I think collectively we have more resources here anyway.
So here's the symptoms. When I'm driving and cruising at say 2500 RPM and I let off on the gas to shift or to coast the engine will hang at 2100 RPM for awhile (10 to 30 secs) then it'll drop to maybe 1100 and hang there for a bit before dropping to idle! If I apply the brakes, it seems to make it un hang sooner. Sometimes though, you can tell it's still hanging when the brakes are applied because it starts to lug the engine before dropping to an idle.
I've tried moving the cable, by adjusting the bracket held by the two bolts. No improvement, I can't see this being the problem because there is a strong return spring to close throttle bodies anyway.
So is it an intake leak, if so what do I use to spray around the manifold to locate the leak.
Or is it an electrical problem with my PCM, which I've read some of you talk about.
It seems to be getting progressively worse and almost dangerous because the car wants to GO. Also for shifting it's a pain. Sure I can drive and get around, but it starting to really p!ss me off. This is not how this thing is suppose to work.
I could sure use some help please!
