So check engine light came on and I took it to Advance to run a test and it come back as an IAC malfunction. I took it off, cleaned it with break cleaner let it dry completely. Put it back on and everything was gravy for a bit then the check engine light came back on. So I got a used one, put it on, (cleaned it before hand) and the check engine light is back on. The car has a high idle (1100-1500 range) and runs like shit after about 10 mins of driving.

Am I missing something?

 

idle air control valves once cleaned will only last a week or two. time for a brand new one.

 

But what are the chances that the used one we got was fucked up as well? Ill try another used one and see where that gets me.

 

yea chances are that one was bad to there kinda funny after they sit around they like to stick

 

don't buy use parts as oldody16 says buy new factory iac

 

Get this hoe to the top cause after installing a BRAND NEW IAC, the check engine light is back on. It is throwing the same code at that. Insight please?

 

Possible ECU or wiring problem, or connector corrosion. Borrow an ECU and see what happens, inspect the connector, and do a continuity check from the ECU to the sensor. If the ECU has been taken out of the car ever, look to see that the IACV contact pin didn't get misaligned and shoved out of the connector housing.
