I was just wondering has any one had this happen to them. My HHR will on occation go into a reduced power mode, Usually if i'm messing around and smash the gas. It'll seem likes only two cylinders are firing, with a ugly sputter at idle and only rev to 3grand and 25 miles an hour tops. I'll have to shut the car off wait for a minute or two and it turns back on running fine. The check engine light will be on for the next few starts and then it'll go away.

I have a 2.2 auto with a B&M shiftplus shift kit, I'm thinkin it might be the shift kit freakin the comp out, because I noticed that it does it more often once i flip the kit on. But not too sure because it's done it a couple times without the kit on.

What do you guys think? Any one else running the shiftplus or have similar problems?

 

Do you know what code is being set?

 

I'm not even sure??? Any way to tell?

 

stop by autozone, advancedauto or a large auto parts chain. they should read the codes for free
