Recently I had high idle that indicated a bad throttle body/position sensor. After investigation notice previous damage to throttle body pcm housing where the plastic connection is located. As well as the plastic harness that plugs in to the throttle body. I manage to replace both throttle body and harness with a new pigtail from nissan but throttle body from o'Reilly. An replaced oil cap with one from o'Reilly as well but as I go to program with 2sec on then 10sec off 2sec on then 10sec off wait additional 10 sec then turn key on for 10sec then off. Turn the key on for 3 sec then press gas pedal in 5x in 5sec then wait 7sec then press and hold gas pedal down until engine light stop blinking with in the the next 3 sec after the light stops blinking let out the pedal and start the car within 20sec but still nothing. In the mist of the swap I notice oil in the intake manifold and wiped that out as well. I have a new batt. an a new alternator. And do notice oil leak on valve cover itself cause of the oil/dirt buildup on the valve cover. Please advise.
