I got a jet performance power control module and put it on my cobalt. It worked fine for 2 days and then last night after work I started my car and it ran for about 20 seconds then got rough and stopped. Then wouldn't start. I took the pcm off and hooked the computer back. Now it works fine. Anyone know about this????

 

i dont even know what your talking about haha.

 

What part is confusing?

 

do not ever use a chip like that! you'll be lucky if it didn't hurt ur engine. chips are a major MAJOR no no.

 

I don't think it hurt anything. It actually runs better without it

 

thats what hes saying haha. chips are no good.

 

I know that now haha. I'm not sure if I can get my money back for it or exchange it though
