Is that,or fouled spark plugs or clogged injectors.

No more codes or missfires, all my other cars have used Bosch Plat.

Thanks for all the comments. Think I'll go OEM.

On today's vehicles if the vehicle engine designers thought something else was better-they would have had it in there. The newer ecotecs run the best with OEM-like the motor was designed around them. Why waste your time & money.

Spark Plugs

I am going to add to this thread. I have a 2006 HHR 2LT with 107K miles on it now. Sometime around 75K I took out 4 AC Platinums and put in 4 AC Irridiums. The car ran worse on new Irridiums than with the old Platinums. I checked and re-checked the numbers and the plugs were correct for the application.

I decided to try E3s since I had nothing to lose. They are still in the engine and on a 740 mile one way trip I averaged 31 mpg figured with long division.

I am a believer in OEM AC spark plugs. I just didn't like the way the car ran with the Irridiums in it.
