Question about 2000 Pontiac Firebird
I had the same problem, obd2 said cyclnders 1 and 3 were misfiring. After changing the spark plugs replace your coils. they are about 20-40 apiece. If you arent able to do it yourself or have a friend do it expect to pay 150-300 dollars depending on the mechanic and the amount of coils.
