Ok, got a question.... i got an turbo ek coupe, 98 to be exact. converted from obd2 to obd1, has a b20 block, b16 head, and b16 trans. Car has RC 550 injectors, aftermarket fuel rail, pump, adjustable FPR... SO today randomly i went to start it and it had a prolonged crank, once it started it was idling at about 400 rpm's for a second or two, thenm jumped up to 750 and CEL came out. Checked code and it was for o2 sensor, but i have no o2 sensor! Never had this issue before, ran good. Car is chipped and tuned, and when you drive it, if you ease your way into throttle, it'll drive fine! full power, spools, and everything.. but if you snap throttle the car jerks around and studders, almost like it's not getting enough fuel or spark is off or something. Firing order is correct, Fuel pressure at idle is perfect, all injectors are firing. I've also tried to reset ECU, and have tried using different ECU's. Any ideas are welcome, as long as they are well educated guesses! lol


Nothing was changed, drove somewhere, parked, got down and 15 minutes went back to my car and it started doing this. I'm stumped!

Well now you do. Either add one or remove it in the tune.
