Car is a 1996 Integra with a b18b that I swapped myself. Transmission is an s4c that I got with the motor. I'm running an obd2a LS ecu. Harness is an obd2a GSR as the shell is a GSR.

When I start off in 1st gear the car jumps forward and back like a person who just learned to drive a 5 speed is driving. It also does it in second after you switch to second if you don't work the gas/cluch just right. It won't do it if you press the gas harder than a person would when accelerating normal. Engine revs perfecting smooth in neutral. I have been driving manual since I was 15 and I drive my girls type s and my friend's cars just fine so it's not an operator problem.

I thought it might be a clutch problem so I replaced the clutch/flywheel/throwout bearing. The problem was not solved. The only CEL I have is secondary o2 and I've never heard of that causing this problem. Or of this problem happening to anyone for that matter. Does anybody have any suggestions? I've been driving the car like this for nearly a year and I'm about sick of it.
