    BINGO we have a winner. Faulty O2 sensor. Replaced Front o2 sensor. We are running perfectly again. Stupid thing didn't fault and was showing it was fine on my OBDII Scanner. Even took it out, blew it out and replaced it checking the connection while I was at it. No Fault. Replaced it and...

    Surging when just start driving.

    Coolant Temp sensor is fine. Took off the front o2, it was pretty clean, no buildup and reinstalled, haven't gotten the back one out yet. Drove it, Still same problem. Wish these o2 sensors were the same part number.

    overheating only when i tow???

    You can still run the transmission cooler for the colder weather, just plumb it in so that fluid flows from transmission to cooler to radiator instead of trans to radiator to cooler. That will prevent the transmission from heating up the radiator, but still keep fluid heated up during the winter.

    Surging when just start driving.

    Did you replace the front or rear o2 sensor or both? Will check the Coolant temp sensor, though it appears to be functioning correctly and mirrors the reading on the dash gauge with the OBD scanner. I've paid attention to all connections. No Rust/corrosion or Frayed wires on any connection.

    Surging when just start driving.

    OK So I was wrong about the MAP sensor fixing this. It is still occuring. Fuel Pressure reading is constant 49PSI from start, Through the Bogging down of the engine and surging. So it is not Fuel related. There are still no Codes on my OBDII Scanner. My Scanner shows live data. What my...

    Surging when just start driving.

    Map sensor tested low voltage. Unplugged map sensor and problem went away, though Idle sucked. Replaced Map Sensor and now all is great. In the trouble shooting I now have a new CPS, TBS and Fuel pump module on the 12 year old Jeep, so they should be good for another 12 years and I have spare...

    Surging when just start driving.

    Replaced fuel pump module. Still same problem. All I can come up with now is air leaking into the fuel line at one of the quick connect junctions.

    Surging when just start driving.

    Well Now I have a spare CPS. Bought one from Napa. Still same problem. Old one tested fine on the multi meter. I'm thinking this is a fuel issue. It's acting like there is air in the fuel line. After driving a 1/2 mile or just putting the throttle to the floor, it runs fine the rest of the trip...

    Have the light duty springs and got 1.5 inches over old springs on my 99 with 60k Miles after settleing for about 1 year. Now I'm adding OME Add a leafs. I'd personally go with the mediums. Skip the HD, they are only help when you have such a large load that they are compressed down to the...

    Wow! XJ's aren't cheap!

    Got my stock 99 4x4 with 44k miles. Paid 5000 plus a 2001 dodge intrepid with 98k miles on it. I got the car free from a family member several years earlier. I think the asking price on the Jeep was $7600. A low mileage cherokee will be hard to find. I searched for 3 months to find the right...

    Full Size Spare. Worth it?

    If you are comparing the donut vs. a full size, then yes, absolutely worth it. Get a cheap steel wheel and tire. If you already have a full size and are asking about a matching size spare, that in my opinion would depend on what you use your jeep for. If for extreme trail riding, then a matching...

    Locker in front or rear?

    Yep, doesn't know how to drive for the equipment he has. I went with aussie in the front. A) because I had one that I stole out of my CJ, so it was free. B) the Aussie 8.25 is like $60 more than the D30, C) The logic that Aussie has on their website about this topic is sound, Here it is; A...
