Hi friends,

I'm new to this forum. I have a 1998 Audi A4 1.8T and the CEL came ON last week saying that car is running too lean ( P1136- Maf Sensor Failure).
So I bought the MAF sensor cleaner from Autozone and cleaned it today.

After driving 10 miles CEL came back ON. The codes are;

16684- Random/Multiple Cylinder Misfire Detected

16688- Cylinder 4 Misfire Detected

This is the first time I'm getting these codes and happend RIGHT after CLEANING maf sensors.


So will this be a problem of the MAF sensors itself? Shall I go ahead and replace the maf sensor?

Please advise.
