ok so i'v been chasing these misfires since i bought the car the misfires are mostly on cyl 4 , 3 and 2 rarely on 1. so far i replaced all the IC piping , some vac lines, breather tube , turbo intake tube , DV , plugs , coils , maf , cts , fuel filter , o2 sensor , ICM. what else could it be i'm thinking either the ecu or fuel injectors how would i test these.

edit: forgot to add i mostly get the misfires on the highway around 2k rpms and above it seems the audi forums aren't much help i miss my dsm people and having people at my house to help after i post haha
