Why does my 99 pontiac grand prix gtp supercharge keep stalling


I would check the idle air control valve before replacing anything.
The computer regulates the idle speed by controlling the amount of air entering the intake thru the throttle body.
The valve could be faulty, or the throttle body can be gummed up.
Is the check engine light on ?

My 2004 gran prix (gtp) just hit 100000 miles. What maintenance needs to be done now?


Spark plugs, transmission fluid and coolant change, supercharger oil, air filter, fuel filter, tires, brakes, engine mounts, BTSI inspection and power steering fluid. Also inspect the belts, hoses, pulleys and look for wiring damage.

2000 Grand Prix GTP supercharger fluctuates when accelerating


There is no wastegate.

Change the spark plugs and pay special attention to the plug on bank 3. Look for physical damage on the electrode...cracked, bent etc.
Use Autolite 605's copper core gapped to .055" and NEVER run less than 92 octane.

97 grand prix gtp starts then immediatly dies


If you have a GTP these engines use a hi output fuel pump. they use a fuel pump resistor located under the battery tray (look up from under the car) This resistor lowers the voltage to the fuel fump when not in boost mode. because of its locatoin it is prone to corrosion. if you bypass the wires and the engine starts and stays running replace the resistor

97' Pontiac Gran Prix Won't Stay running


Known GTP problem.

You most likely have a bad fuel pump resistor, which controls 2 speeds of the fuel pump.

To check to see if this is the problem, there is a trick you can do and its very easy to do. Go to the attached link, and bend the tab my finger is pointing at and then plug it back in. If your car starts and runs fine, well we just solved the problem.
