2000 Grand Prix GTP gets 13 MPG... I don't know SH** about cars, but it should be better than that! I mean, besides air filters, tires and spark plugs, is there something else I should be aware of that's causing this??

How many miles are on the car?
Cat could also be going bad.

158,000. Like I said, I know nothing about cars and can't waste money trying to fix what it might be, so I appreciate it

At 158,000, I'd think it's safe to replace the catalytic converter. If it's not your problem, it will be soon. Pretty sure they only last ~10 years (which, at 12,000 miles/year, would be 120,000 miles). You know the cat is completely toast when you smell rotten eggs from the exhaust, but it can be clogged long before that state.

Do you notice anything specifically with the way it runs that could help us give a better guess on what you need to do? Somebody mentioned cleaning the MAF sensor, I would do that if I was you, it really helps some cars. It's like $7 for a can of MAF sensor cleaner....If you have carb cleaner at home you might want to also consider cleaning the throttle body of all the buildup. Those are probably not the whole root of your issue, but it's a simple, quick place to start and it will make a little bit of a difference... somebody in your area with a scanner could pull some data off your car and tell you what's causing the problem, could be a variety of things, cat, O2 sensor, etc..
