I have a 95 Civic Si with the Vtec motor. What's happening is this: if I excelerate (usually in 1st or 2nd gear) hard and let up on the gas, then excererate hard again and let up, the car will begin to surge up and down by itself. The only way to stop it is to dump the clutch. If anyone can help me get to the bottom of this problem I would apprieciate it!
