Grand Prix GT 3.8L V6

  • Automatic transmission
  • 55,000 miles

There are a few solutions to this problem, or so I'm told. Apparently it could be the EGR Valve, EGR Sensor, Air Pump, or a clogged vacuum line. I have no idea which one will fix my problem. I have an extended warranty but the deductible is $75. If the part that i need is cheaper then that i don't want to pay more then i need to.

My local repair man came to pick up my car to take it to get an oil change and when he brought it back asked when the check engine light came on? I told him that morning on my way to work it was not on! I know this is a very common problem in a lot of vehicles, I had a diagnostic test run on it which cost still more money!

Service engine light came on and car was sluggish. Catalytic converter was replaced. Service engine light came back on 3 days later but car ran fine. When it came time for inspection, car wouldn't pass inspection and kept kicking out an emissions code. Light was reset, but by the time we could get it reinspected (within a day) the light would come back on. We had to have the catalytic converter replaced again just to have the car pass inspection. The light came back on 2 days later. Service engine light is still on after the converter has been replaced, the car tuned-up, etc. Does anybody have any suggestions?

I need some serious advice or help!!! I have been reading stuff and apparently it can be all kinds of things... First of all the car started to bog and hesitate... so we changed the fuel filter.. a few days after that the check engine light came on, so we took it to have the trouble codes, it came back as the lovely EGR valve!!!!! So we were told the valve is $142 dollars, $161 with gasket... Well my question lies here...... What can I do?? What if its not the EGR, but a sensor, or catalytic converter?? Has anyone else been through this with there crappy Pontiac???

Well to start off with, my wife owns the Pontiac grand prix se, and had taken the vehicle to the all known all knowing all charging dealership to have the vehicle worked on after the service engine soon light came on. The vehicle had a great loss of power and an annoying rattling. The vehicle was "fixed" under the warranty at no cost, and drove fine for about a week, then during our road trip from Indiana to California the light comes on and once again a significant lost of power occured. We got stranded in Colorado for three days since no one in the service department works on weekends. One the forth day we take the vehicle to the dealership where they fix it and in Utah, the next state over the same problem occurs. The first time the problem was the catalytic converter, and the second time was the sparkplugs, BS!, which the charge you a just to run a diagnostics. What kind of mechanics are they hiring that do not know how to fix the cars for the dealership they work for?? Oh yeah and as for the spark plugs, i checked them myself and the dealership mech did not even check the gaps which were wrong!! and left a sparkplug wire dangling on the engine which was burned!! That is some shitty service!!
