Exclamation 2011 5.0 Idle Issue

Hi,

I have a 2011 F-150 5.0 with 101,050 miles and I am experiencing idle issues. Here's some info:
  • Battery just replaced because of starting issues, battery tested BAD
  • Idles at ~650 RPM at 13.9~14.0 volts
  • Low oil pressure light came on one time since issue has started
  • When tapping the throttle very lightly, the RPM's dip to ~375RPM and ~12.2 volts. This happens in reverse, drive, brakes applied and brakes not applied.
  • Normal throttle acceleration has no issues. Only very light throttle taps like when in reverse cause the issue
  • Please see the video I made:
Does this sound like an oil pump, oil pressure sensor or alternator? I'm stumped.

Thanks!
Robert
