Having problems with your 1997 Pontiac Grand Prix ?
I got a p0171 code and I can't seem to find the any kind of vacuum leak and car is overheating drastically
Possibly a blown head gasket throwing off the O2 sensor? Do you have a lot of moisture coming out the tailpipe?
I would call the car dealer, he can help you with the code.
