My 2003 Rubicon is at the dealer now.Same Problems your having.They tell me it is the angle sensor.Will let you know this week.

 

The mechanic that fixed it for me told me (superficially) that the connectors were making bad connections. Somehow I have heard this before and it is right. He did clean all the connectors on the machine and then he resetted the computer. I have 1300 miles on the machine and it is FANTASTIC!!! Let me know what the dealer tells you.

 

Finally got my rubicon back from dealer on saturday.They replaced the angle sensor.Took it for a short 20 km ride yesterday.So far so good.I will keep you informed.
