I have 2001 Audi Allroad with multiple missfire when the car is cold and sometimes having a code for a missfire on cylinder number one and on cylinder number six. I changed spark plugs, checked the coils and swapped them. I did check fuel pressure vacuum leaks, I checked the timing and no luck.
P.S.: the codes for missfire and actual missfire is mostly on the cold start but when the car warms up, you barely can feel missfire. Idol is still not like it supposed to be.
