my 94 chevy s-10 is missing sporatically on the 2nd cylinder. i replaced the head gasket and checked the valves. i put new plugs,wires, and injectors on plus new coil packes and had the module tested. could it be an electrical problem or the computer?

I would start with a compression test and if that is OK, an injector balance test.
