Question about 1999 Pontiac Firebird
Did compression check it went all to cylinder 3 being the misfire now the shop that has it says there is something wrong with 4. they say it runs good until you put a load on it. you can drive it till you try to stomp the gas then it has a little hesitation.
I had the same problem with my firebird and i'd try changing the plugs and wires first and if that doesn't work try changing the coil pack for that cylinder. Those are the main components that make your cylinders fire.

I dont understand,
what were the compressions readings for each cylinder?
Please list and when you find a low cylinder put about a spoon full of engine oil in the spark plug hole and re do the compression test and send me that result also please.
