My 1998 328is has a occasional misfire at cylinder #6. It comes and goes whenever.There is no set time when this happens. I replaced the plugs and coil pack. Could i have a computer problem? Maybe faulty wiring at the injector or coil pack?

to test the ECU, good people quick turn around just send them the computer. Check the wiring in case a rodent has damaged the wiring and check for wiring issues.
