My engine surges at idle to about 1100 rpm. It does not always do it. My mechanic has checked everything out and can find no problems. He confirmed that the O2 sensors are good and that the IAC valve is good. There are no fault codes set. It does not matter if the engine is hot or cold when it happens. Any thoughts?
