Question about 1992 Pontiac Grand Am
My 92 pontiac grand am SE 5 speed has been acting up lately. It will start...then quietly die. When i go to restart....it backfires loudly, sounds like it is coming from under the car. It will take several times of trying to start and backfiring before it will start and run. It does it intermittently....and I never know when it is going to die and not start. Please help.
It sounds like to me you are having problems with your fuel injectors. In situations like these there are soooooo many different variables and possible problems, but the fact that the car is backfiring makes me believe that you are getting too much fuel in because that is what makes are car backfire. When fuel makes it to the cat converter or muffler it will burn there and cause the backfire. My suggestion would be to start the process of elimination with a good fuel injector cleaner. The only one that recommend is called Greased Lightening and can be purchased at Napa and O'Reilley auto parts. If you don't have one of these near you I would go with Techron. Let me know if I can help you with anything else. Thanks for letting me help you with your problem and I would appreciate an honest rating on the help that I gave you. Thanks for using FixYa!
