"Engine is running well, although since the 'event' on rare occasion it will "burp" when idling! Just skips a beat and goes on. Only once mind you. Weird... ... "
Davison,
My engine was doing the same thing. I checked fuel pressures and every thing--all good. It would not go away, and just miss slighlty every now and then at idle with the engine warm.
I added Power Services "Bio-Cleen" or Bio Clean, to kill anything growing in the tank. That eliminated it for me.
And I do remember the first time it started was just after I filled at a truck stop... Best of luck
