Idle Problem - Cleaning Idle Valve?
I have the same 'hunting' idle problem that so many other people seem to experience. However, I have tried all fixes, including cleaning the idle vale. When I stripped it down, it was spotless, with a small amount of clean white grease inside.
When people talk about cleaning it, do some get filthy inside? I am at the end of my patience with this issue, having already changed the MAF, the lambda sensor and thoroughly cleaned the throttle body. There are no leaks in the air pipe and the car runs fine once its rolling.
Strangely, it is fine when its cold, the problem only starts when it has reached normal operating temperature.
