94 Ranger bucking/stalling - SOLVED !!!!
I have a 1994 Ranger 2WD with a 2.3 engine (2 plugs per)... Manual transmission.
I rebuilt the engine and truck some years ago for one of my kids. It's ran PERFECT with no problems whatsoever. Since then, the truck was passed down to my youngest brat. It has been sitting for 2-3 years until he got his drivers license.
Fast forward to today...
The truck still runs GREAT. Purrs like a kitten; HOWEVER... when we took it out, the check engine light keeps going on/off and the truck intermittently stalls/bucks at lower speeds. The truck runs great, but it's as if you are turning the ignition switch on/off. When it stalls, you can back off/on the gas pedal and it will run fine until it does it again. It does this most often at lower speeds, but I also reproduced the problem while sitting in the driveway in neutral when revving the engine fairly high. Engine revving... poof... no nothing... bump the gas and back on it goes.
The only time it doesn't happen is when the truck gets up to highway speeds.
If I'm reading the OBD code flashing correctly, the computer seems to be tossing a code 57 which has to do with the neutral safety circuit? That switch is on the clutch pedal and works fine. Besides, I don't see how that switch would cause the engine to die while on the road. The CEL and the cut-out may not even be related; however this all seemed to happen at the same time.
The CEL has NEVER came on since I rebuilt the truck. This has somehow happened when it was sitting. I've checked all connectors, the TPS sensor, MAF, etc.. all seems to be fine. I've checked all relays, fuel pump, etc. What am I missing?
It's clearly an electrical issue, but where do I look? What makes the engine shut off dead cold and then back on again when you bump the gas peddle?
Sorry for the long post, but I thought I'd give as much information as possible. As most of us know - intermittent problems, especially electrical ones, SUCK!
Thanks,
SJ
