Hello, I'm in need of a service manual that covers the powertrain and other components of a 2006 TJ Rubicon. I've been having codes pop up on me and decided to invest in a code reader. I bought one from Snap-on and it does a lot. It tells me real time data and what the O2 sensors are putting out. What I need to know is what is beening displayed is within perameters or needs attention. If somebody could lead me in the way of this I would be greatful, and able to get my rig back on the trail. I have called the local dealership and was told they would be happy to diagnosis the problem but will not give information out. Thanks for the help.
