To tell you exactly, what happens is when I accelerate (to redline), the car will pull hard up to 4000rpm then taper off at 5500rpm and then continue to pull hard past 5500 to redline. So its like; "weeee, ahh shit, weeeee". I thought it was the clutch, but my mechanic friends said it wasnt because when a clutch goes, its usually consistent in high RPMS and they also did a "stalling in 4th-gear at a stop" test and the car even passed that. Any of you have ideas what it could be? I was thinking fuel filter...possibly pump? Thanks for looking
