Question about 2002 Pontiac Grand Prix
It's a possibility the injector is the problem. It may not have the psi it needs, therefore the cylinder could be misfiring, or the injector could be letting too much fuel in. Before I change the injector, I would try to have someone to clean the injection system to see how it works. The cleaning around in South Carolina is $99-$149 depending on where you go.
