Default Log insight, please. - 05-13-2022, 10:14 AM

I have been chasing the craziest idle issues, stalling at low rpm, not to mention low power. I have changed the plugs, coils, injectors, hpfp, maf, tmap, and serviced the transmission (130k miles).
I just had the hpfp replaced yesterday with the hopes of improving the idle and rich mixture however, no luck it seems. With that stated, the car feels super flat from 3-5k (or so), but then magically comes alive and feels pretty great after.

Please note, I am running the lean BEF posted for f series as the car does seem to run smoother when lean. Running lean actually stopped the stalling from happening at low rpm (speed bumps or stop and go traffic) prior to swapping out the hpfp. I have yet to run the car on the normal pump flash as the mechanic mentioned yesterday the car was still running rich.

Thanks in advance to all who review. Hopefully the data helps.

Whelp, missing bung in my VRSF charge pipe was the issue. Smoke test first kids, don’t replace everything hoping for the best.
