: Overhead trip computer question.

03-03-2009, 03:07 AM
The only option I have with my ZJ is the over head computer. Its nice and I use it frequently to answer some questions. Lately its been cutting my mileage in half. (i.e. if i drive 100 miles, i can turn it off and come back the next day and it will read about 50 miles)

Any thoughts or past experiences you guys could share, is it just the computer in the over head going bad?
