Please help someone!
Recently i have had right drama's with the idle on the car. The engine is the x20xev. The problem i am having is the idle keeps sitting around 1500rpm. This is not all the time, usually when the car warms up, and now i have an even more anoying problem which has started. The idle now sits at 1500rpm and goes up to 2000rpm and drops back down and back up and back down if you get the picture!
Does anyone know what this is? I have taken of the throttle body and ICV and cleaned them thoroughly with carb cleaner and its still the same. It did seem to stop for a little when i first put it all back but then after a little drive the problems back.
