Question about 1999 Pontiac Firebird
Pulling p300 code. Changed plugs, wires, coils, injectors, and lifters. Still pulling misfire under load. What could cause this?
It could be a clogged fuel filter, bad gas. Or if you have done alot of modifications to it, the injectors may not be able to keep up.
