      I've been doing a bit of driving with my old PCM and it is so smooth on the idle and acceleration! Much nicer. So far no shuddering and...

      It is a Wranglerfix PCM. I might put my old one back in to compare. Andy

      I think the problem I have is transient - bank one goes into a strange state then back out of it again. Lots of misfires.

      With ignition on and fully warm, sensor 1/1 is toggling between 0.1V and 0.88V. 2/1 is toggling between 0.1V and 0.8V. However 1/2 is...

      For the last few years I have been fighting constant problems with B1S1 O2 sensor. P0133. I replaced all four O2 sensors with new NTK...

      I installed the front stabilizer bar a couple of years ago, following the FSM and torquing it as required. Now that I look at it...

      That looks like a lot of bump stop. At ride height how much distance do you have for up travel before the bump stop bottoms out vs how...
