The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

When the window is not used often or gets a little older the motor can "Hang Up" You might try having someone hold the down switch on the drivers door while you slam the door. This will sometimes jar the motor enough to make the brushes contact and start working.

This is likely caused by a burned out alternator, charge the battery, verify it will hold a charge and replace the alternator.

Can I replace my 98 grand prix driver's seat with


You can replace it as long as the one you are replacing is the same set-up. If you have a manual adjusting seat and replace it with a power seat it will fit but you wont have the hook ups for it. Also make sure if it is a bucket seat (single person) you dont replace it with a bench (3 persons fit in front) seat or you will run into problems with the center console and shifter. vice versa may bolt up but there will be a gap between the 2 front seats

98 grand prix 3.8 non-supercharge starts but wont stay running have to keep foot on gas pedal to stay running blows out white some trough the exhaust. no coolant in oil what is causing this


If it is blowing thick white smoke that is coolant. You can lose a head gasket in places where only coolant passages go through so you don't always get oil/coolant mixing when this happens. Take the radiator cap off and see if air bubbles through it. You can also try pulling the spark plugs to see if one or more looks really clean.
