Hi, im new here. i just bought a 2001 audi a4 quattro 2.8l v6, i knew it had a check engine light when i bought it and a bank 2 sensor 2 code. I changed the sensor and the code went away. it also has a multiple cylinder misfire code and misfires onf cylinders 1,2,3. i thought it might be the spark plugs so i canged them and its still misfiring. ive since swapped the plug wires and installed a new coilpack but still getting the misfires. if i reset the fault codes and drive the car, the fault codes wont show up again until im idleing. i wanted to check for vacuum leaks maybe but im not sure which are the vacuum hoses. can anyone help with any ideas? or a diagram pointing out the vacuum hoses would be helpful too. thank you.
