Need help figuring out what these codes mean???

Asked by Apr 29, 2016 at 06:55 PM about the 1999 INFINITI I30 4 Dr STD Sedan

Question type: Maintenance & Repair

I ran a diagnostic tests for a friend today using
one of those  code readers for your car, and these
codes popped up (in this order): P0300, P1130,
P0300. But I'm having a hard time figuring out
what these codes mean. My friends car smells like
it's running REALLY rich when turned on and ran,
and like a whitish color smoke comes out the
exhaust. However there is no water in the oil to
suggest a cracked head gasket. PLEASE HELP!!!

First code random misfiring, Next P1130 (defective harness/connector or Swirl Control Valve Control Solenoid Valve) The Swirl Control valve is in each cylinder intake and when close, speeds up airflow to improve fuel atomization for better fuel consumption. The SCV is open when the the engine is at Idle or when below 3200 RPM, provided the coolant temperature is from 50-122F. The SCVs are closed at high engine speed 3200RPM or high temp 131F or very low temp 50F. Regards
