I bought this crx hf cheap from this kid. He swapped a d16z6 into it. He bought the obd1 jumper harness and shit. The car runs like shit for the most part. It idles at 1500 rpm, spudders from 2000-4000 rpm then will open up after 4000, and the vtec doesnt work. He told me when I bought it the thing needed the vtec p28 ecu. I dug in and looked at it and it was the p28 ecu. Im confused now. I was kinda looking for the diagram for the black loomed solid wires that comes off the jumper harness something tells me its in that. But im not sure anyone else had a simular problem or know where to get the diagram. This is kind of a nightmare.
