well I did new plugs and coils on bank 2,., cylinders 4 5 and 6,..and it did'nt change a thing,So I fiddled around looking for a place to use my vacuum gauge , I find a little plastic line under the intake...I gauge it reads nothing I could not build any vacuum at all take the TB and tubing apart,..find oil in those intake tubes and the TB plate was all greasy ,..then I found a small black plastic tube shoved into a rubber hose,it didnt pull vacuum either,.So Iam going to rebuild those vacuum connections and then check it again..Also the AOS is about a year old. thanks Frank
