Misfire at idle

Asked by Donkingey Dec 07, 2018 at 10:28 PM about the 2009 Audi A4 2.0T quattro Premium Plus Sedan AWD

Question type: Maintenance & Repair

Deathjam, i have a 2009 audi a4 2.0t quattro. Car
would have trouble starting sometimes and when
starts it bogs out. Didnt have the time to really
mess around with it. Then i did a topend seafoam
cleaner and got codes of intake leaks and o2
codes. Then lately the CEL lights would come on.
Also didnt really looking into it due to lack of time.
So i let my cousin borrow it couple weeks back
and he deff hotrodded it and brought it back with a
bad idle. I ran the codes and had misfire on cly
2&4. Spark plug on 4 was wrecked. Changed out
coils and spark plugs on all 4 cylinders and still
misfiring with CE light still blinking. 4th cyl was
wet. What could be the issue
