Also mate, thanks for your reply. im just going off what my tuner is telling me. I'm not a tuner by a long shot. he is saying on start up the car won't start first go because it has a 4 second delay to register what fuel is in the sensor?? when you first start the car it revs then stalls. Then on the second start it will start. is that normal? before when I was running just pure 98 the car would start first kick.
