Hi, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially and if the idle is good, then it would appear to be a fuel delivery/starvation issue. Proposed preliminary checks (if have not been done) on suspects:

  • • drain tank and replace with fresh fuel (even if just to eliminate as a suspect);
  • • test fuel pump output pressure (least likely);
  • • check/clean fuel path (likely);
  • • check/clean the injector (most likely).

The video tutorial HERE on injector cleaning may shed insight.
