Hello I own a 1993 honda civic ex it has the original motor(150,000miles) but has a idling problem as soon as the engine starts it goes all the way up to 3000 rpm an stays there for about 10 seconds then it surges between 1500 rpm an 2500rpm an doesnt stop. When I turn the air conditioner on it will sometimes idle normal. When the car is cruising it will slowly accelerate with my foot off of the gas pedal I have tried a tune up an still no luck im thinking it is the idle sensor or oxygen sensor but im not sure.
all information will be greatly appreciated Ryan
