Won't rev past 5000 rpm
#1
Ok. My s4 NA will NOT rev past 5000 rpm. it's also very sluggish. it has good compression ( 110-110-110 on the front rotor, 100-100-100 on the rear rotor), a new fuel filter, good spark on all 4 plugs. the secondary injectors are within spec resistance. i have good continuity on the plugs for them. I just got a new MAF from a junk yard and it's within spec. Anybody have any ideas?

Do you still have catalytic converters?
I once had a customer who had similar symptoms and it was a clogged converter.
He had an exhaust shop cut out the clogged cat and reweld it up with just one good cat and some straight pipe.
Maybe this is it???
