No, I really don't know how it happened. This car has had an idle fluctuation for a long time. It would rev up from 1000 rpm to 18 or 19 hundred rpm, back and forth while in Park or neutral. I messed with changing the IAC valve twice, but got the parts from salvage yards because of the age of the car. It did not help the situation. So I finally took it to a mechanic(not a honda dealer) and the car came back to me in worse condition. He also changed the IAC Valve, with a junk yard part, and put tune up parts on (rotor, cap, wires and plugs). Now, the car idle fluctuates between 1000 and 1200 rpm while cold, gets a little better once it warms up, but had a check engine light come on and would pulsate while driving.
But I still can't figure how any of this could bend a valve. Anyway, I talked to a Honda Mechanic who told me the first thing the dealership would do is replace all the tune up parts with OEM Honda parts. So I went ahead and bought the parts and did the work myself. The wires were a perfect fit, as well as the rotor. The check engine light is gone, the car sounds good, but still has the idle fluc. I guess I will take a stab at that this weekend.
thanks for the reply
