check engine light came on.

My check engine light came on last night. I did the key 3 times and got the code p0129. From what I can find on the net, it is for Barometric Press Too Low. Any ideas on a fix for that?

Also my fuel gauge has started work incorrectly. When you fill it up, the gauge doesn t move. I was able to turn off the key and turn it back on, then the gauge would work. But that trick is slowly starting to not work. Is there anything tricky with these?

A shot in the dark here......could the barometric pressure thing be a bad gas cap?

It would help to know what year and what your Jeep is made up of? http://www.jeepforum.com/forum/f9/fi...ofiles-402432/
