I have a problem with my Cav 2.0l 8v, what happens is when I am driving along and I dip the clutch for stopping and the revs are below ~2000, they will then drop down to anywhere from 500-700 depending on how much electrical equipment I have got on. Then recover to normal idle, I think the ecu is catching them?
It used to only happen when I was stuck in traffic and stop starting, keeping the revs under 1000. But now itís all the time. So guys any help with whatís causing my problem?
Now I remember it this also happens when I start the car from cold they go up then drop to 500 then idle normally again, when its doing this the battery light comes on but not in the circumstances above.
