Question about 1997 Pontiac Firebird
Have replaced plugs, wires, fuel pump and filter. also changed maf sensor. still idles ok. runs good for first minute. then when I try to test drive it falls on its face. also changed coil packs and ignition module.
Have you checked the fuel pressure with a gauge, and is the check engine light on ? TPS check out with a meter ok ?

spark plug gaps are very critical on computerised cars!! [some wont even start!]
distributor module may be breeaking down as temp rises they fail!
otherwise do compression check as it may have valve problems
also check plug leads & injectors aswell as the fuel pump pressure [ could bestarving for fuel]

A misfire doesn't always have to be ignition... it's just the most common cause. Faulty or plugged injector, low compression. You need to check fuel pressure and test the fuel injector flow. Then check compression. If you don't have tools for these tests, take it to someone who does. Testing is much cheaper than throwing parts at the problem.
