Im having a po300 code and cel on. 2011 370z Nismo. 32000 miles. Car sits alot. cel comes on. ,Increased idle 1000-1100 rpms. Outside of the high idle car runs fine. Its in the shop now. but owner isn't to sure what direction to go forward. im going to have them check for vacuum and air intake leaks. also exhaust leaks. Only mod is fast intensions exhaust. factory cold air intakes, No cats on car. Theres all kinds of reports on here so its frustrating at best, all original plugs and coil packs . THX D
