Asked by Lostdieselmech Jun 16, 2018 at 04:49 AM about the 1998 Mazda B-Series B2500 SE RWD

Question type: Maintenance & Repair

1998 2.5L Mazda B2500 (or a Ford Ranger ) Code P0171. I have changed
spark plugs/wires, fuel pump, intake manifold seals, egr seal, pcv valve,
multiple vaccum lines (both rubber and plastic) and rubber elbows, fuel filter,
both O2 sensors, no exhaust leaks, no intake leaks, the fuel rail pressure is a
consistent 35 psi. I am about to replace the PCM for lack of other options. I
have asked multiple talented fellow mechanics, and they are still not sure. I was
hoping for some additional input. Please help this poor truck before it goes in
the swamp. I am a diesel mechanic, and I am having my career choice put to
the test by my around the town "beater" while I build my diesel truck.
