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.

I got audi a6 2.8 lit. The engine misfires especially on low revs on 1st and 2nd gear. When revs increase misfire decreases. I have changed spark plugs and leads. Tested in audi preston diagnostics - no...

I have a 1999 A6 2.8, and my car was doing the same thing. However, after spending about a $1,000.00 I took it to another dealership. they replaced the fuel filter, it was dirty from putting cheap 91 gas in the car. Once it was replaced the car ran like new. I had to replace it around 80,000 miles. Hope this helps
