  1. ESS quit working

    My ESS has been in charging only mode for months. I'm going to take it in.
  2. Help me understand how my clutch pedal failed...

    This is my 5th MT and by far the hardest to get smooth engagement when starting from a stop. I have the muscle memory but every once in a while I either stall or over rev the engine. Actually it really takes away from the driving enjoyment. Every start is a new adventure, and not in a good way...
  3. Wrangler Rubicon JLU 3.6 engine pre-detonation

    My mitigations are to stick to 93 octane, and keep the rpm's above 2000 at all times. The pinging seems to happen when the air temp is warm, the engine is warmed up, and the engine is under load below 2k rpm. The pentastar is no low end truck monster but a high reving car engine.
  4. 3.6 engine and 87 octane a no-no

    For me its a therapy session because I can't force FCA to make the factory tune better. 😊
  5. 3.6 engine and 87 octane a no-no

    About the lugging, yes, 1 mitigation is to wind out the motor more and always keep the rpm above 2k. It helps but there are times where it's not easy to maintain the higher rpms on hills and in traffic. Its funny how the Jeep rides like a truck, is high up like a truck, but the engine is really...
  6. 3.6 engine and 87 octane a no-no

    The pinging occurs when the engine is fully warmed up and the ambient air temp is at least 60 degress, under load at rpm's in the 1500-2000 range. In the MT its easy to reproduce. I use 87 in winter and 93 in summer. The 93 helps but does not fully stop the pinging. I doubt 93 helps with power...
  7. 3.6 engine and 87 octane a no-no

    The pinging is also a strong function of ambient air temp. In winter here in the North, 87 is fine. But once tbe weather warms up, I switch to 93 to avoid the pinging.
  8. 3.6 MT Stalls in Reverse

    I have stalled this vehicle more than any other MT I have owned. There is a learning curve.
  9. New JL Steering Issue TSB 08-074-20 (for "Improved Steering Feel")

    I got mine done today. Stock Sport model. It steers like a different vehicle, in a good way! The dead spot is gone and the steering is heavier. It's so much better. In the old setup the dead spot was about 2 inches. Now it's gone, or as small as any other vehicle. Anybody on the fence should...
  10. V8 Wrangler Rubicon 392 Concept drive review by MotorTrend

    The 4.0 could be efficient under the right conditions. My XJ got 25mpg on the highway. I once got 500 miles on 1 tank. I was down to fumes.
  11. anyone makes a lower temp thermostat ?

    Since many people report the engine knock at high temps, it would be interesting to see if a lower temp would keep the mixture richer, therefore eliminating the knocking. The theory is the mix is too lean at higher temps.
  12. Clutch Recall (FCA W12 | 20V-124) on 2018-2020 JL Manuals [overheating clutch pressure plate]

    The old BMW clutch delay valve. I had an E90 with that and it was never smooth until I took out the delay valve. Then a few months later kid number 3 was on the way so I traded the 330i in on a 3 row Subaru.
  13. Engine Knocking

    The last vehicle I drove that knocked was a 1987 Chrysler Lebaron. A modern engine should never knock, thats the purpose of the sensors. So no matter what a manual says, its a problem. I can often keep the RPMs above 2k by delaying when I shift into the next higher gear when accelerating. With...
  14. Engine Knocking

    There are several discussions on this topic in the 3.6 subforum. It's a common problem. The consensus is that once the engine gets up to operating temp, the tune is too lean and you get knocking under load conditions at low RPM. Until there is a new tune, the mitigations are to run higher...
  15. New JL Steering Issue TSB 08-074-20 (for "Improved Steering Feel")

    I think its the manufacturing variability in the original part that causes the wide range of differences. Could be different suppliers or factories. I would hope FCA QA would have good specs that would weed out the bad ones. But apparently the slop tolerance is quite high. And FCA finally gave...
  16. Steering issues....solved!

    I like the idea of waiting for an actual fix. I wonder if you could order a new box and then test it and send it back before its installed, and then rinse and repeat until you get a decent box.
  17. Opinions on the manual transmission

    I turned off the Hill assist and I feel a difference when starting out from a stop. Here is western PA, you're always starting on a hill. By a difference, I mean I don't feel the bog and mushy engagement, like before.
  18. Engine studder and thottle lag anyone else having this issue

    Today I turned off the Hill Start Assist, and the clutch feels much better. What I mean is that the engagement feels normal, no more of the vague, mushy engagement where you have to hope she doesn't stall cause the RPM's have dropped too low. I suggest everyone try it. It could be the...
  19. What actually _is_ normal steering?

    The dead spot and wandering are not normal for a solid axle vehicle. My 95 Cherokee had solid axels and no dead spot or wandering. I put almost 100k miles on it and these issues never crossed my mind.
  20. 2020 Steering Feel

    The crown of the road makes a big difference also in how much wandering is experienced.
