just want to clarify that you are running a dual point intake on a mulitpoint head? correct me if i am wrong, but you should be having problems.
you need to correct the situation by getting a si intake and doing the wiring for a multipoint injection. you should be using obd1 injectors and ground the resister.
you need the ecu for your d16z6 head which is an obd1, 92-95 distributer, the P28 and do the wiring mods.
sounds like you need wiring help as well.

I see people out there spending money on the car to improve it … If you spend half that effort just working on your driving skills, making you and the car work together as a team, then you’ll go faster – period. To make the car go a second faster on the track takes a lot more energy and money than making yourself drive it one second faster.
