For a couple of weeks now my car has been idleing weird and i thought maybe it was a vacuum leak but there isnt any. I then took the icv out and cleaned it up real good but it still didnt work. Would u suggest buying a new icv or is there anything else that it might be?
Did you test the throttle position switch? They burn out after a while. Look in the Bentley manual there's a proceedure in there for it. Basically test for continuity in the switch when the throttle is closed, then again at WOT. It tells the computer the throttle is closed and turns over idle control to the computer. You can also unplug the TPS and see if the idle settles down. But with the TPS unplugged you won't get the bump in rpm when you turn on the A/C, and cold starts will be a little harder (you have to give it a little gas while cranking...). Test for continuity with an ohm meter (digital multimeter...) between the correct pins.
