I have a 97 audi A6 Quattro 2.8 12v. The car was running fine before i pulled it in the shop. I removed the rack & pinion and rebuild it and put it back in. Ever since then the car sounds like its running on 3 cylinders and cant breath. I looked at all connectors and the wires are still in the back. So if anyone can help that would be great. Because i'm lost. Thanks
