Question about 1998 Audi A4
Could it be that i need a tune-up, which is due, or is there some other problem and could you advise.
A tune up wouldn't hurt. You could also trace out the plug wire for the misfiring cylinder and see which coil pack it's attached to. Swap that coil pack with another and then see if the misfire stays in the original cylinder or if it moves. If it moves, it's a bad coil pack. If it stays, I'd look into new plug or wire for that cylinder. Beyond that, have the injector in that cylinder diagnosed to see if it's failing.
