1998 gtp grand prix, engine light came on and the car started to
As soon as my engine came on the car started to spudder while driving and is realy under powered. When I give it gas the engine starts to flash but still hesitates. The car has 128,000 km and I just drove it to northern British Columbia where there is quite the difference in altitude about 2200 ft, I dont think that has anything to do with it

So ,yes you can!
i think it's time to replace the battery. have you tried to crank it after someone gave you a jump? if it starts than replace the battery. there's no real way I can tell you how to check the charging system unless the car is running.
my 1998 grand prix does the exact same thing. It just shuts off while driving. I still have battery power. I have called pontiac dealers in my area and they dont seem to have any idea to fixing without changing everything in hopes the hit the problem Can you narrow it down.
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
