Review on 🔧 GM Genuine Parts 217-435 Idle Air Control Valve for Fuel Injection by Joel Wright

The engine has a rough idle, only when cold, but runs fine at normal operating temperatures. I learned the hard way to only replace electronic parts with genuine GM parts. Well, there's still a problem. There are no codes on my OBDII scanner. Further testing of other components revealed that the EGR valve had burned out. Have to order a new one but the OEM is over $100. I think I'll get a replacement EGR valve from the standard equipment. Hope this solves the problem.
