i got a 95 ej1 w/ a h22a...well today i was driving and while shifting into 5th gear my gas peddle stayed down and i shifted into 5th while the car was reving up...after that i pulled the gas pedal up with my foot and i put the car in 5th gear like normal, but when i pressed on the gas the car kinda shook and than the clutch wouldnt catch; the car just revs up... I can hear the flywheel or something turning too... Whats wrong with my car?? and how much will it cost???
