I had a problem with sluggishness on my 95 gt 5-speed. I took it to a shop who did a back pressure test and said all cats were shot. I put on a high flow H-pipe, (BBK and not a very good fit) It fixed the overall accel up to 3500 RPMS, but after that you arent going anywhere. It takes for ever to climb past 4500 and sometimes wont do it at all even if you hold it to the floor for ten years. I could bever get it to redline although I dont plan on it. What is up even when the rpms slowly rise the speed stays the same. What would cause this?

 

your clutch might be slipping. that's almost exactly what my CRX was doing just before my clutch gave out.

 

WILL THE CAR REV PAST THE 4000 RPM MARK SETTING STILL NOT IN GEAR? IT IS NOT YOUR CLUTCH BECAUSE THAT WOULD LET THE CAR REV UP IF IT WAS SLIPPING.
