Bonneville 3800 Series II SES Check engine light is on and the computer is reading EGR valve and bad gas from Autozone scan. I know my car has a lot of miles but I just put a new motor and water pump in it
Code U3f00 I have and engine light code Uf300 in the PCM. The emissions test won't run the oxygen sensor or catalytic converter tests.

Pontiac Won't Start Even With new Battery I own a 1997 pontiac bonneville and when i try to start it there is a loud clicking noise and all the lights flicker i was wondering if it might be the battery that causes this even though i just put in a new one.
3800 coolant sensor Replacement am having a bit of a problem, I need to replace my Coolant Temperature Sensor on my 1997 Pontiac Grand Prix SE 3800.

Firebird Runs Rough When Wet 1997 formula firebird 5.7 LT. When rains or wash vehicle engine runs really rough. Car will die if you dont keep idle up until it somewhat dries out, engine lite comes on. Had new spark plugs and wires put on the car by someone who does know what he is doing.

Bobby said: Reply @Bill french: A 1966 Pontiac? Backfire through the carb are usually a sign of a bad cam shaft. One or more of the lobes is worn so the valve is not opening all the way, or not at all.

marty said: within two days of each other two windows quit working. If you hit a bump they window starts to slide down and you have to pull them back into place. this is on a 2000 grand prix gtp supercharge 4 door. We now have three windows that this has happened to. Would this be a case of window motors all going bad at the same time or corrosion on wire connection.
Hank112 said: Reply @marty, if the windows are sliding down into the door and you can manually lift them with your hands, then the window regulator has broken, or at least the glass is not attached to the regulator anymore. You are going to have to take the door panel off to see.
Stanley said: @michael, You could have a plugged catalytic converter. That will cause a big loss in power. A stumble when accelerating is usually a bad spark plug wire.
Pontiac GTP MAP Sensor Live chat: Where is the MAP sensor located on a supercharged Pontiac Grand Prix GTP 3800 motor? I cannot seem to find it . I found pictures of regular engine location, but not the supercharged. Also,the blower speeds are not working. I replaced the motor and resistor already. What else could be wrong with my car?
