    My 90 civic has been running great but I haven't taken it on any long drives until recently. It drives fine for about 20 to 30 minutes and then it sputters and won't maintain a constant speed, you have to pump the gas to keep going. Once I turn the car off, unhook and rehook the battery, I am good for another round. Obviously, its electrical related but what? I am running a B16a with a PW0 ecu and no O2 sensors. (the PW0 needs two O2s in the header otherwise it surges and I plan on getting the ecu chipped this summer) I also have the fuel pump hooked up to a seperate switch because of a fautly fuel relay. Has anyone experienced these symptoms?
