After 7 faultless years with a 97 XJ Sport that died, got a stunning 98 4.0 XJ with only 70K. It runs of petrol (as we say here) and lpg. Ran perfect on lpg but rough on petrol. Changed injectors, throttle body, all sensors, lamda on exhaust, not only was it no better, the dash then failed and gearbox went into limp mode.
Have subsequently replaced gearbox solenoids, gearbox control unit, . We then took it to a Jeep main dealer for diagnostics ,turns out the ECU was not original but they set it up with their kit, still no good, the nub of it is the the ecu and gearbox aren't communicating , on the dash the orange key light is on and the speedo and rev don't work. To cap it all last night all the electrics died. It is far too good to scrap. Anyone got any ideas? I'd be really grateful !!!1
