Re: 2001 Accent GSI Idle-Surge problem
My o2 accent did this, I don't know if it's the same or not (I have a 1.6l) anyway there is a silinoid on the throttle body that I think controls the air input in motor.Take it off and there is a little metal flap inside that rolls up into unit. Myne was carboned up real bad. So I took some rubbing alcohol on a q - tip and cleaned as well as I could. MY car had this problem at about 20,000 miles, no problems since I'm at 40,000.
