Engine dies at idle speed
I just replaced a faulty ignition control module,
truck starts and runs well. But dies at idle speeds,
could it be the 2 prong contact is plugged in
Sounds like a bad IAC (Idle Air Control) valve. HTH. -Jim
Thanks, stupid question where do I find it? My other chevy knowledge is a 68 C20 custom ordered from factory...
The IAC will be on the throttle body. It screws into the throttle body and has a 4 way electrical connector plugged into it. HTH. -Jim
Hey all, new problem with idle stalls. Well same problem. I have replaced the idle bypass valve, throttle position sensor, and egr valve. After egr the idle became even worse climbing up to around 2k rpm then dropping off and stalling out, and is now running very rough. Any thoughts on what I am missing here?
