I recently purchased a 2003 Audi A4 Quattro 3.0 v6. It has 151,000 miles on it. I got a cylinder 2 misfire code so I changed the spark plugs and the coil packs and a few days later the cel came back and the same problem. So I got a new connector for cylinder 2, soldered and can haves that but still have the cel for cylinder 2. I am new to these cars so any help on what the problem could be?

 

It must be that you have problems with the cooldand system ( Check all hoses )
