98 Grand AM 4cyl.
My pontiac is misfiring, could it be a bad computer? My mechanic seems to think so, I just wanted to verify. At low speeds, like take off it misfires, and coil checks good. The computer indicated only misfiring, check engine light came on, said it was running rich. Light goes on and off.
Could also be spark plugs or coil wires, and yes it could also be the computer.
