This has started to happen frequently along with idle surging up and down. I've cleaned the IAC, but it doesnt help. So do I need a new IAC possibly along with a TPS?

Also, i have been posting abouy my car having problems after cam and headers. The problem was fixed with new plugs, wires, and coil.

 

could be egr or vacuum line?

 

Paul,
if anything might be wrong, then it's probably the IAC. The TPS doesn't usually go bad.

PS. I sent you the files.

 

Thanks Ion -

I sent you a PM
