a quick question about injectors. what would happen if i use obd1 injectors (not sure of all the terms, peak n hold, etc), the kind that dont use a resistor box, and i hooke them up with the resistor box.

im wondering because, on my b18a swap (obd0) i noticed my fuel rail has injectors with grey clips (obd1 or 2), but i sitll have the resistor box and the obd1 ecu, so im wondering if the guy i got it from put teh wrong injectors in. the grey plugs were spliced onto the wiring harness, would my car run weird, i noticed it seems liek it lags a little, but im wondering if it would affect the performance. does this sound weird?
