My 1192 gmc sierra idles correctly with the map sensor unplugged


did you clean the port before you replaced the iac valve, and measure the pntle before putting it back in, whenyou buy a new iac valve you can't assume the pintle(needle) is correctly placed. the pintle shldnt exceed 1 1/8 inch past the body seat, it can be pshed in by hand, then after it's pu t back in cycle ignition on for 10 second (do not start) then turn ign off for atleast 10 seconds, this allows the iac valve to reset. then start engine.
