i have a 2004 audi a6 3.0 quattro with 136,000 miles (mainly highway) and my engine
keeps misfiring first time it happened i took it in and they replaced the engine coils
and that worked for a while but now (4 days after coils were replaced) its misfiring
again. Why, and how do i fix this problem?
have you ever changed the sparks plugs? if not change all 6 should fix the problem, and check the spark plug wires. what kind of trouble codes are you getting?
I got it taken care of timing was off
