I swapped in a hybrid engine a while back in my 93 Acura Integra. I have a B16A block and a B18C1 head, ran off of a B18C1 ECU. My problem is that occasionaly the car will surge and buck while accelerating. I thought It may be the O2, but I have no CEL's and it runs fine most of the time. I am getting a new Distributor tommorow, so i'll see if that fixes it. Any other ideas?
