Question about 1999 Audi A6
My Audi A6 Quattro 2.8 misfires when warm. I have changed the Plugs and plug leads, but thr problem persists
You may have a coil pack going bad. They're on the front top of the engine - you'll see them if you follow the spark plug wires back. Do you have any codes from having the engine scanned? If you can get it scanned (AutoZone will do it free), post the codes up and we'll see which cylinder(s) are misfiring. From there, you can swap coilpacks around and see whether the misfires follow the packs or stay in the original cylinders. If they move, you have a bad coil pack or two. If they don't, since you've already changed plugs and wires, I'd see about having the injectors diagnosed to see if any of them are failing.
