Interesting info, but I would have to know what the specs are for the vehicle rear travel distance, and compare the difference to see if its within manufacturers specs.

Hi, What is the typical life of rear coil springs? My 2002 liberty with 180K miles, is getting a bit soft in the rear. I measured the distance from the ground to a point on my hitch with an almost empty fueal tank, filled it, and noticed a drop of half an inch, is this normal? The vehicle has...

Here's the update on the sensor issue. The P0138 problem was fixed for now, the tech attributed the fault to gease on the coonectors and wires. The latest code is a P0158, the right side dowstream sensor, dealer ordered a new one and the tech made a mistake and replaced the dowstream on the...

Ok, I'm starting to hate oxygen sensors. The problem with the left bank upstream O2 sensor was caused by dirt or gease on the connector contacts. Now another sensor code has popped up "P0158', this is a heater circuit high voltage on the right side downstream sensor. A new unit has been ordered...

Not yet, will know by tomorrow. Thanks for clarifying "PM', sort of new to forum abreviations.

How do you check power module for more info? As I mentioned yesterday, the vehicle was at the dealer and tech is seeing a voltage on one of the connector pins with sensor disconnected. This could be a short somewhere between the PCM and connector. With no sensor connected the only wire that...

Well, the problems continue, after replacing both mini cats and upstream o2 sensors, I was expecting a better fuel mileage and normal power, this didn't happen. Also, the misfire problem is still showing on the ODB code reader despite having swapped coils and replaced #2 plug. Decided to leave...

Again thanks for info, will have mechanic replace the right mini cat and o2 sensors tomorrow, and as well try to resolve misfiring problem.

SteelHeadz, thanks for info. How do you reset the adaptives for the pcm? Do you reset with an ODB2? Also, the rough idling, I learned is caused by poor or no spark on cylinder #2, according to ODB2 error code P0302. This could be a bad plug, ignition coil or wire, or combo of the later. Just...

Hi I'm new to the forum, so I hope I'm not repeating this problem. My 2002 Liberty with 282,000Km(169K miles) had an engine light warning two weeks ago. I had my mechanic put the diagnostic tester, and it came up with error code P0240, problem with the left mini cat. I had it replaced, the...
