If you're cruising in 6th at 70-80 and mash the gas, and the engine starts to rev, your clutch is done. Try that. Mines doing it right now.

You mean engine BRAKING.

I didn't know WTF you were talking about. Was your car tuned? You can set RPM decrease by speed, maby someone tweaked it?

Mine doesn't slow down very fast if I downshift, but it does slow down.


Brake is the thing on the floor. Break is when a rod comes out the side of the motor.

well quit holding it there, let your foot off the gas.. lol

weird my car slows down pretty good with engine braking.. not very good on the crappy 10 bolt rear though... if in neutral and your foot off the gas do the rpm's drop fast from 3k rpm's?
