either the chip in the key is bad (try the other key) or the receiver on the back of the ignition is bad. If both keys dont work there is nothing you can do but have it towed to the dealer.They have to replace and reprogram the unit and the keys! I am sorry.

Sounds like the same problem I had. I brought it to the Jeep dealer and they told me that the heating element in the seat stopped working. They told me that the only way to repair was to take the seat apart and replace the heating element in the seat. Of course they will charge you the standard $80 to tell you this. and then quote you $500 plus to repair. I can't even remember how much, I have decided it was not worth it.

Your catalytic converter is not doing it's job efficiently enough and it is setting off your sensor. This problem is emissions problem and usually has no effect on the operation of your vehicle( unless the converter clogs) As long as you don't live somewhere they do emissions test you don't really have to worry about it. However if you want to fix it you can take converter off and run a straight pipe or to do it "right" you could go pay way to much to get a new converter put on.

The OBDll system will need to be reset with a scanner. Waiting for the computer to do a system can take time and mileage.

Three possible solutions:

1. Bad Thermostat

2. Fan Relay (most likely)

3. Bad Fan

When the GC reaches a temp of 180 Deg. F the fan relay sends a signal to the fan to turn on, once the temp lowers (around 155 Deg. F) the relay turns off the fan, and so the cycle continues. If the relay is bad there will be no signal to the fan to run. While you are driving your vehicle there is ambient air moving thru the radiator, cooling the engine, but once you encounter slow/heavy traffic or stop there is no air moving and the temp goes up, the fan will not kick in and the vehicle will overheat.

If the fan motor is not working the same will happen, but a more expensive fix, as the motor comes with the fan.

If the Thermostat is stuck in the open position, the water travels to fast in the engine and heat exchanging is not an efficient process, therefore the vehicle might overheat when stopped or in slow traffic.

With all the problems, you might have a module problem. Make sure it is alright.

Sounds like the relay that runs the fuel pump. The computer may be reading no oil pressure and shuts the engine down Check the oil pressure when it starts with a manual gauge. You may need to prime the oil pump.

Steve is right on the money. You engine is staying cold too long. I assume you probably don't have hot heat like you use too either.

If there was a trouble code, the code should tell you which one? bank 1 or bank 2, and or sensor 1 or sensor 2. Bank 1 on a v engine is the bank with number one cylinder. Bank 2 is the other bank. Some sensors are labeled upstream and downstream in relation to the cat, before or after. Upstream is senor 1 and downstream from the cat is sensor 2.
Is it clear as mud?

I would check to see if the vehicle had an accident and the inner panel or insulation was not installed or not installed properly. Check the under side of the vehicle on the passenger side and make sure the rocker area is not damaged if the vehicle went off road and hit or landed on s large rock. If you have a vent not the inner kick panel, the vent may not be closing if it is electronic or the vent is not closed completely.
