    Alright guys I'm super new here actually first time on posting in a forum lol. So I've been having an intermittent super rich condition usually when turning in 2nd gear my afrs are around 8.6 to 9.2 and my fuel pressure is around 1700 to 1800. I replace the wiring harness and that worked for 2 months then cleaning the maf once a month worked for a while but now it randomly runs 900 to 1100 psi fuel pressure at idle and bogs like crazy. Also the hpfp voltage is 0. It's so intermitten I can't datalog it. Any thoughts?

    Mods: bnrs4, jbr 3.5in intake, gfb bpv, occ, catless dp, corksport 3port ebcs, corsport, 3.5 map, hpfp internals, zoom power exhaust manifold, act clutch, megan racing coils, working on dizzy custom tune

    Are you sure this isn't SWAS related?

    Definitely disconnect swas and see if that solves it before spending any more money on parts

    I'm not sure if it's SWAS related mainly because it'll still have stupid ltft and random stft at idle and cruising such as -20.44 ltft and random -25.4 stft then go to -.66 stft sometimes and seems to have better trims when a/c is engaged

    You can disconnect seas for free in about 30 minutes. Try that first to rule it out since most of what you are describing points in that direction
