Check gas cap? 2004 Pontiac Grand Prix?
I have a 2004 Pontiac Grand Prix, my check gas cap and service engine soon light keeps popping back on. I took it in to the pontiac dealer to be fixed they said that my fuel injection system, and my entire fuel system needed to be cleaned I paid 400.00 dollars and took my car. I thought the problems was fixed until I recently went to take my emissions and it rejected my car they said I needed to drive the car more because my gages or whatever hadn't reset...today as a matter of fact I called my service advisor from pontiac and they agreed. They reassured that those light wouldn't come back on the problem was fixed just drive the car. Guess what? The lights have come back on..I'm taking it back to the dealer tomorrow but I don't want to keep paying for things I don't need. Please don't say its the convertor because I have already done that as well(and I had to purchase the original one1200.00 dollars!) it's the only one that would work right with the grand prix, I use 93 octane gas, and yes I did replace my gas gap(three times to be exact) factory installed. Any advice I would appreciate

In order to be of use to you, please try to obtain the code that the check engine light is prompting. By the way, you got taken for a ride on the catalytic converter. Any muffler shop could have replaced it for about $250 and it would have worked absolutely fine.

Before you go buy that cheap aftermarket crap. Be aware that a lot of them do not meet GM's minimum emissions specs. They build them to meet their specs, not the car manufactures. I have seen new aftermarket gas caps cause the same problem. I suggest you just go get a AC Delco of GM brand part & replace the fuel cap. An emissions leak will never have anything to do with the MPG, maybe after a million miles of driving, it might affest 5 MPG but not in the car's lifetime. I never go by the IPC display on what it thinks it is getting ever, its just a best guess by the computer. Do the fill up gallons divided by miles driven will get you the most accurate results

Could possible be the Fuel Tank Pressure Sensor. It is located on top of the fuel pump. To access it open the trunk, pull the carpet back behind the back seat. Remove the oval shaped access panel. The AutoZone part number is su1390.

You might can reset the com. and lights be removing the negative wire on the battery. The air temp sensor went out in my wifes cavalier when i replaced it the light still came on. I disconnected the neg wire for a few hours then hooked it back up and it has been of since. the shop might do this and charge an arm and a leg.
