Pontiac Problems? Ask a Mechanic for Answers ASAP
Hi, I’m Ron and I’ll be helping you today.
Before we get started though,Please understand that I don't know your skill level or tools you have to assist us. Also understand that I can't see,smell, hear, or touch the vehicle either, so patience is appreciated.
My goal is to make you happy and get a great rating in return for my time.Sometimes I have to give you bad news that I know you didn’t want to hear, so please don’t shoot the messenger.
2 different problems may be here, 1 would be a bad fuel gauge, the other could be a partially blocked CAT converter. The best thing you could do is attach a scan tool and monitor fuel trims, and a vacuum gauge to monitor the loss of vacuum.
So what were the results of the scan? That's what we were supposed to do first.
