I am new to the forums as a member, but have benefitted from your knowledge over the last year as my son and I have embarked on the fun of Jeep ownership. We have a 2007 Rubicon 2-dr, Manual Transmission.
I have come across a problem that is similar, but not the same, as many others.
Currently it is doing the following:
1) The vehicle will start to feel sluggish. I can feel a physical deterioration of the power.
2) The ETC lightning bolt comes on and the engine immediately starts to sputter.
3) After a few seconds the ESC light will come on.
4) If I push in the clutch the engine will die (see pictures of 0 rpms at 55mph) and I lose power steering.
5) If I don’t push in the clutch, it will die and re-engage immediately from “clutch popping,” but I lose power steering in the process.
6) If I either pull over, or turn the vehicle off then back on while still rolling, the lights will disappear and the vehicle will run nominally, until it does the same thing again.
7) If I do not pull over to restart, the vehicle enters what I assume is a limp home mode, and no matter how hard I press the accelerator, it slows me down to 20mph, even on the freeways of South Florida (incredibly dangerous to be on in a tank, let alone a malfunctioning top heavy wrangler).
I have noticed there is no connection to when it happens.
Hit a bump, stopped at a light, sitting in the driveway, in gear, in neutral, while accelerating, while decelerating, when it is hot, when it is cold, when it is wet, when it is dry.
I have checked for ODB codes and found none, there is also no MIL illuminated.
Below are corrective actions I have taken to attempt to diagnose:
- Pedal position reset a dozen times to no avail.
- Currently waiting on a new throttle body to come in (later today).
- Inspected the wires going to the throttle body and all seem functional; No rust or corrosion, pins are all seated, and there doesn’t seem to be any issue regarding harness tightness.
- Checked battery connections. All tight and free of corrosion.
- Used trickle charger to fully charge battery.
- Checked alternator to ensure ~14.2v output: All good.
It may be important to note that we did have a new Centerforce clutch and B&M shifter installed. But as no other posts I have read so far have mentioned anything related to the transmission, I am not sure it is related.
Any ideas, directions, or other help that anyone can provide in solving this issue would be greatly appreciated. Thanks in advance.
