SOURCE: having trouble locating my idle air control valve

looking at the throttle body assembly, after removing the air filter housing, opposite side of the spark plugs, about an inch or two down, you should see a electrical connection, with four wires, the IAC has two small torxs screws that hold it to the throttle body.

SOURCE: How to locate idle air control valve?

It's located on the left rear of throttle body assembly. I looks like a small metal cylinder with two bolts and an oval plug with 4 prongs. Yes you can change it yourself. If you can't find it, go to your local auto parts store and have them show you a picture.

Check for vacuum leaks. Leak causes O2 sensors to sense too much air, then computer tells injectors to run full rich to compensate.

2003 chevy 4.8L truck wont start unless you give it gas any ideas


it sounds like the device used to control the idle speed is the problem. This is the IAC, idle air control valve. check the electrical plug going to the valve for security. The valve can be removed and cleaned with spray carb cleaner. Clean the throttle bore and plate as well. check for broken or disconnected vacuum lines. Lastly a stuck or clogged PVC or EGR valve may cause similar problems.

You may need to replace the IAC.

go to autozone.com web site. they will have a tutorial on how to test and replace IAC.
