Engine Performance problem
1999 Pontiac Firebird 6 cyl Two Wheel Drive Automatic 116000 miles
they told me my car was misfiring on multiple cylinders and they told me it could be the injectors coils or the plugs and wires but I replace the plugs and wires last year so how do I know what is wrong. They misfires get worse at higher rpms if I keep them low the car feels fine until I step on the gas.
have the same problem?
