So my 94 ranger quit on me a year ago, just getting around to messing with it. It's currently doing the same thing it did back then. Runs pretty good cold. But once it's warm it idles normal but will drop to 400ish rpm at times. No power at all, just barely can get it to roll down my street.
Nothing was changed before it failed before. it just screwed up on its own. The o2s are new-er and I did retorque the intake at some point.
I just changed fuel pump and filter. Also spark plugs and wires. Drove it around and when it decided to bog down I got the following codes:
629(koeo) Torque Converter Clutch circuit fault - Transmissions
566(koeo) transmission 3/4 shift solenoid/circuit - Transmissions
565(koeo) Canister Purge 1 solenoid/circuit failure - Solenoids
556(koeo) Fuel pump relay primary circuit fault - Power / Fuel Pump Circuits
159(koeo) MAF sensor is/was out of range - MAF
177(koeo-memory) Oxygen sensor not switching - system was rich Left or Front HO2S - Fuel control
137(koer) Oxygen sensor not switching/system rich Left or Front HO2S - Fuel control
Was talking with another member on here and he figured MAF, I bought a new one, reset codes, and still have same issue, except the memory code of 177 is gone.
He's thinking a wiring issue? Any other ideas? Tests to preform? Its been so long since ive messed with it i dont really know where to start anymore. Also i noticed i only have a left o2 code, since it's not both maybe it could have a problem with the left one?
