I was driving my truck to church last night and it started missing at around 60 mph or 2000rpm and above. It would not do it under heavy accelleration. Fuel pressure is around 5psi at WOT and it does have the intank retro fit any ideas would be greatly appreciated.

Thanks

I've met a few mysterious misses in my life, but that's for another forum.........

Where is the fuel pressure guage located? Pre-filter = dirty filter - post-filter on VP44, next step.

What was in-tank fuel level?

Wet air filter?

Wet\salty\oxidized\corroded connectors.

Any DTC's?

Injectors usually symptomize llike that, where missing can be felt at steady rpm, but not under intense acceleration.
