Hey guys, this is my first post but I really need some help. I've a 2000 A6 with the 4.2 v8 and I've been dealing with a multiple misfire situation for awhile. When I pull codes I get a misfire code for every cylinder plus the random multiple misfire code but no other codes such as bank too lean or anything you would imagine from a fuel issue. I've replaced all coils and plugs, as well as fuel filter and coolant temp sensor, and all new vacuum lines. I've cleaned the TB and done the alignment a billion times. Someone point me in the right direction.
