I have a 2004 Audi A4 1.8t
getting codes that reflect misfire on #2 and #4 and code for random Misfires
replaced all 4 coil packs with dealer parts. and replaced all 4 spark plugs with dealer parts. Still have same misfires and now the car is harder to start have to depress gas pedal to start. Occasionally get rotten egg smell from exhaust.
Anyone have the answer.
