ok I have a 99 civic dx, which I swapped a jdm sohc d16a (OBD1). The car will start and once it warms up, will hold its idle. The only codes that were pulled were, my o2 sensor, intake sensor, and vtec. We fixed all but the vtec (the dx harness doesnt come with vtec). After fixing those two it still ran shitty (but a little better) so I started looking at the harness that came with the car and realized the wiring around the fuel injectors has been cut and respliced or something and when I wiggled those wires the car cut out. Another thing is that the dizzy wires were switched to fit the harness. Any help will be great, I want to get this car running soon.
