99 Jeep WJ with the 42RE. Took it out for a shakedown run after the axle swap. First time I have driven the jeep for more than 10 minutes since I have owned it.
We are on the first trail of the day and about 15 minutes into it, i go from park to 1st gear on the shifter and try to accelerate and the jeep bogs and dies. I put it back in park and try again. Same thing over and over. It wont move. It will idle in gear just fine, but once you press the gas pedal it will try to move and then stalls the engine. It does not have these symptoms in reverse. It will sling rocks in reverse. Put it back in any forward gear and floor it and it stalls.
Towed it off the trail. It runs ok on flat ground but lacks power. If you try to accelerate hard it falls on its face. Try to powerbrake and it stalls. Put it in park or neutral and you can floor it and the engine will rev to the moon and back without hesitation.
Replaced fuel pump
Replaced fuel filter
Cleaned throttle body
Scanned for codes (none present)
It only does this when its warmed up. When cold or after sitting overnight it has no symptoms, shifts perfectly and has power in all gears.
Is this a solenoid problem? Stuck in a high gear? Pump? Clogged filter? Something else? I dont feel like it is engine related because it has 100% power in reverse. This is only when it is in a forward gear does it fall on its face.
Any guru's want to take a stab at diagnosing this over the interweb?
