Went on a long trip this weekend. Half way there the IAC alarm went off. We finished our trip. Then yesterday while flushing the engines the other side went off. This is on a 2007 382 with the 600's. I'm not familiar with where the valves are yet. Is it a DIY job or is there a computer involved? Also I thought it odd that both would act up at the same time. Ground problem maybe? Any advice would be appreciated. Eng. hrs. +/- 180

It is odd that both would go at the same time. If your engines are 600SCi's, the IAC is located on the side of the throttle body and its literally two screws, one plug and a gasket. very easy to replace but it is a little odd that they would both act up at the same time..

Thanks

Noteably when the IAC shorts and throws a code, be prepared to buy a computer. Dustin at Whipple can repair it if that's the case. I replace mine every year. A gm stock part will work. There appears to be no board protection in that circuit
