Pontiac Problems? Ask a Mechanic for Answers ASAP
Hi, I’m Ron and I can help you.I have been in this business since 1975 and also teach automotive repair. I am confident we can resolve your problem together. Please understand that I don't know your skill level. I can't see, smell, hear, or touch the vehicle either, so it may take a few replies to get to satisfactory results. Please be patient!I also try to give all of the information you may need, expecting a “positive rating” in return. I will also continue assisting you after you have rated me, if necessary. If there is any reason I cannot get a positive rating, please let me know why “in advance”, so I can go another direction for you. I am sorry you’re having this problem; I’ll help you through it.
Check the fuel pressure and volume with a gauge, check the filter, and check the exhaust for blockage. Also check the MAF sensor for being dirty inside.
Ok, you need to use your lab scope and start testing the ignition components then. Then you will isolate the problem that way if you are not getting good data from your scan tool. Also, try mode 6 on your scan tool. That always helps too.
