Icon6 91 DX/Si ZC Swap issue
I have a question for the experts. I have a 91 DX that is fully wired as an Si with a fresh ZC swap. My problem is that the car runs and all but when youre giving it gas it "sputters" like its not getting enough gas or something. The other mods are an MSD Distributor, Blaster Cap, new wires, and an AEM Fuel Rail. Any suggestions as to what might be causing the problem?
