The engine surges at idle at times with the ac kicking off. The engine is coding Idle control system rpm low and the first code was the same but with a pending. I was wondering if the is a common thing on these 03 Honda accords. I also was wondering if you could direct me in the rifght direction to fix my problem.

Hi chispis1,

I would suggest cleaning the throttle body and IAC valve as a start. The throttle body and IAC air passages could be dirty and partially clogged causing the low idling rpm and the error code.
