    29F1 low fuel pressure 1/2 engine

    Hey guys, just got done filling my car up (e50 mix), drove away and got 1/2 engine light and a rough sounding engine, almost as if the engine fan kicked on... I parked w/running and ran codes: Got a single 29F1 low fuel pressure code.

    I cleared the codes while running and the engine instantly smoothed out and the code hasn't returned, even after a few hard pulls.

    I logged a few pulls and HPFP is fine, LPFP (stage 1 fuel-it) drops to 61 but for the most part is between 65 - 75 psi. I am running meth so the LPFP mainly dips during meth flow.

    This is the first time I've ever had a 1/2 engine light and this code, however, this is NOT the first time the car has stumbled, hunted for idle and had other strangeness immediately following a fill-up (then it runs and starts fine).

    Anyone else experience this?

    *edit*

    Me fail english... The code is fuel pressure plausibility, not low pressure. Wondering if its just a random code from having a stage 1 LPFP upgrade now..
