Re: 1989 grand prix turbo 3.1 engine

Well here is an update to my earlier thread on the 89 pontiac grand prix turbo.
I did not give up. I kept wondering about the new injectors. I decided to go back to NAPA and ask some questions about the injectors. To my discovery, the ones I had purchased earlier were the wrong ones. They were not for a turbo engine. I ordered the correct ones and installed. Now the car runs real good. So if anyone ever buys injectors, make sure they are for a turbo because they dump more gas when needed !
