Actually, now that ive got my AFR alot better i can actually feel the vibe at cruz.it pulses.i,m wondering is what im feeling is a drone or a vibe.its not horrible but you can feel it.

Try rolling in a fresh set of plugs or gapping the existing a little closer and see if that helps. Assume a Comp test / leak down test has been done and all is good inside ( no weak holes)? Drone / pulsing vibs are usually drive train related?
