ok so im driving to work the other morning and everything seems fine im driving 60mph in 5th gear just cruising no shifting or anything. and all of a suden my rpms fall to idle like i shifted into neutral. so i take it out of 5th gear and start trying to get the car in a gear and i had nothing, i could put the car in gear with the shifter but the car would not move acted like it was in neutral. im thinking my clutch went out but not sure, so yesterday i get in it to steer while my dad and buddys try and push it in the garage and i start the car and it went into gear and drove lol im confused. if the clutch goes could it still engage? any ideas would be helpful. its a 1997 integra gsr only mods are a intake.

thanks
adam
