I've got a 2006 TJ that is giving me fuel problems for the second time. The first problem occurred about a year ago when I got a check engine light. I immediately dropped from the normal 250 miles of a tank of gas to 200 miles on a tank. It turned out to be the Bank-2 O2 censor on the exhaust manifold.
This time I'm not getting a check engine light, but my fuel mileage again dropped from 250 miles to 200 miles on a tank of gas. It also seems to loose some power on steep inclines.
Anyone familiar with this type of fuel problems???
