97 civic ex CEL p1509
Check engine light is on on my 97 civic EX. Code comes up as p1509 IAC Valve Circuit Failure. At around 1600-1800 RPM's or so, the car kinda revs up and down, almost as if your hitting a rev limiter or something. Which gets kind of annoying when driving.. Had a mechanic look at it, cleaned the IAC, throttle body, etc.. And he couldnt come up with anything. What all do you guys suggest? Thanks.
