Well i just pulled it out, but turns out its not that, that censor is just the back up light switch. I lower the transmission and plug it bak on todays butta the car still runs the same. Still getting that speed cut at 3500-4000 help any1?

Check the timing belt alignment. Even one tooth off can cost you power and revs.

A plugged exhaust will create too much back pressure and wont let you rev up.

that was what was wrong with my 89. No power, idled smooth but couldnt get the engine to rev over 3000. It would overheat real fast too. If your car over heats at the same time, I recommend checking the exhaust for pluggage.

That is what happens to cats when they start to clog up too. Chop it off and replace it with a pipe and see if that helps.
