Rev porblem

[BoneDizzle]

I, obviously, have a problem with my car. It is a 90 240sx the the ka24e. In every gear, the car doesnt rev past 5000 rpms. I dont know why this is. It just bounces off 5000 like it is the rev limiter, but redline isnt till 6500. I dont think my speedo is off by 1500 because that would mean i am idling at 2300 and that just isnt so. I am new to the board and i tried searching back threads, but with aol it is terribly slow. any help would be great.thanks - Mike
