You probably have after-ignition, usually caused by operating with dirty fuel. The way a mechanic explained it to me is that there is (very small) debris in the cylinder, on the piston. When you hav edriven enough that the engine gets to a good tempertature and turn the engine off, the debris (if it's large enough) is red hot and causes any small amount of fuel to ignite, thus causing the piston to go down, thus causing more gas to come in to the next piston ready to fire, debris is hot, and it just goes on and on. Seek the advice of a knowledgeable mechanic or get Chilton's mechanic repair book and check the trouble-shooting section. In short, my opinion? bad gas, my friend. Change gas stations.

Firebird?
A 2001 Pontiac Firebird is a rear wheel drive vehicle
the two bolts, one on each side of the egr valve.
NO! the Montana is a front wheel drive minivan and the firebird is a rear wheel drive, even if they were both rear wheel drive for some reason, the firebird engine would shred the wimpy minivan trans and it would be just wrong to put a minivan trans in a firebird.

This site has a step by step guide for an older Firebird, but it is identical to what you need for a 2001. http://shbox.com/page/windowmotor.html
Turn the key to the run position, pul l the pcm ign and pcm batt fuses from the fuse blocks under the hood. Turn the ignition key to the off position and then reinstall the fuses. It will take about 75 miles for the computer to relearn but that should lower the engine idle.

Check the 2001 Grand Ams crank shaft position sensor first. If the sensor is bad then the engine will not get fire or start.
