cant figure out this idle problem

jonk00000 · 05-12-2007, 04:42 PM

when my car is warm, it will idle high between 2500 and 3000 sometimes 3200. any ideas on what would cause this?? ive changed my iac and tps done gaskets on tb and checked for boost leaks. i know some off these things wouldnt affect idle but im just tryin to rule things out.
any ideas will be appreciated

have you adjusted the idle screw on the the TB?

yes it makes no difference

would anything in the thermostat housing affect idle?, sensors ??

Did you check the throttle cable?

you must have idle malfunction. i read somewhere on the forum before on how to fix it. i would suggest finding out by looking up the thread and trying those ways to fix it. if not you'll need to replace it.

throttle cable is probably the one thing u have left to fix. It was good u replaced the TPS because that's probably the only other thing that would give out the same problem u have now. The throttle cables on these cars can go bad, bend and snap. They're the cause to floating idles. U probably wanna have a look at that.
