i have an s13 with a redtop sr
-fmic and full exhaust
-walbro 255
-stock boost with an s14 t28
the car runs pig rich at idle. like in the 11s, (i have a wideband) and starts going lean after 4k rpms ive done the following
-boost leak test
-changed fuel pump
-new z32 fuel filter
-wired fuel pump directly to the battery has 13.5 volts running now
-changed fpr with known good one
-changed maf
any ideas? it has to be an electrical problem. it started after i let my car sit 2 days without a battery and relocated the battery to the back seat due to puncturing my old battery i had up front.
someone point me in the right direction please
