ok so today I was driving and my friend was behind me and noticed that my car would smoke under boost when shifting...he couldn't describe what color it was cuz he is an idiot but it was smoking none the less. My ko4, plugs, and injectors all have only 3k miles on them but I must say I'm overdue for an
oil change. The car runs mint but I decided to vag it anyway and pulled a random misfire code and a cylinder 3 misfire code, and also noticed that the knock sensor voltage at cyl 3 was lower than the rest. Does anyone kno what this could be...possibly coilpack? Someone help!
