06 Aud a4 2.0T misfires?
Hey guys so I had a problem 3 days ago where my check engine light turned on. I was on a trip when my car turned off and acceleration where above 1, So I took it to the local Autozone and gave me the error code that was crankshaft sensor and misfire on cylinder 1. I continue on my trip and when I arrived to my destination I tried changing the spark plugs. After I was done I turned on my car and the check engine light was blinking and car was vibrating. I then saw that a ignition coil was faulty. I changed cylinder 1 and 4 ignition coil with new spark plugs. Car worked great for a couple of hours but then check engine came back again and when I accelerate my car kind of lags and takes a while to respond. I have now multiple misfires (PO300-P0304) and PO322 ERROR CODE.

Did you put a new crankshaft sensor in it? If not, that is probably the problem not the coils. The ECU gets primary timing information from the crank and camshaft sensors. If either of those two sensors is having issues, it will misfire. The misfires will cause the other error codes too. Until you get the crank sensor swapped out with a new one, the other issues will not go away.
