The coolant temperature sender was also broken. The instrument panel inside the car had been jumping around for a while. It would continually go on and off so we figured it'd probably be a loose or broken connector. However, when I took the connector off the sensor I found that half of the sensor was actually loose.

The sensor had broken in half which explained why it was working on and off randomly. We replaced the sensor with a part from NAPA and it's fixed completely now.

We had also been having some issues with the idle on the Jeep. The idle was very low and stumbled quite a bit. On several forums I was suggested to clean the IAC, or Idle Air Controller. This IAC controls the amount of airflow in the bypass channel on the throttle body. Usually when you are idling the large butterfly valve, which the throttle cable controls, is closed. The only air flow control into the car is the bypass channel at this point which as the same suggests bypasses the butterfly valve. This IAC has a little part that can move back and forth to control the airflow in the bypass channel. The IAC was extremely dirty and after cleaning the idle was at a perfect 650 RPM and no longer stumbled. I also cleaned the throttle body while I was at it, it can never hurt. To clean the IAC just remove the 2 torx bits holding it against the throttle body then slide it out. This is what it looks like when clean:

The car came with a leather wrapped steering wheel from the factory. However, this leather had been disintegrating lately. After driving the car you'd be left with sticky hands and a steering wheel that would come apart in your hands. So I ordered a WheelSkin cover for it. Because of the large spokes on my steering wheel I knew this would not look perfect, but to be quite honest, I'm really happy with the cover and it sure beats the cheaper ones that are not stitched on.

The center console had been squeaking ever since we got the car. It wasn't so bad unless you accidentally hit it or drove off road, it would squeak as if the end of the world was coming. I fixed this by using some silicone window sealant where the plastic was rubbing against each other causing the noise. It did take some time, but now the center console is quiet and makes no more squeaking noises.
