Re: OBS 7.3 “stutter” issue
Sounds like your 97 may be a California model. Cali 97s have splitshot injectors, a fuel pulse damper on the top of the fuel pump banjo assembly, and a shunt on the Glow Plug Relay (along with GP monitoring circuit wiring). It will use a DPC-312 PCM
with MME series code. The DPC-312 PCMs are very hard to find and pinned out completely different than the DPC-202 PCM
used in the 49-state (Federal) trucks. I am unfamiliar with your Fuel Bowl fuel flow mod nomenclature, so what exactly is that? What's your fuel pressure look like at idle? You might need to physically remove the chip and see if the stutter remains. Cheers!
