Hello, I just had this problem happen the other day. I noticed that at 45 mph my '92 Wrangler (6 cyl..150k mls) started vibrating pretty bad. Then this morning I noticed that my fuel gage was going down pretty quick. I used a 1/2 tank of gas to go 18 miles!!! Still vibrating!! <img src="/forums/images/graemlins/scared.gif" alt="" />. So I changed rotor and distributor cap in case I was misfiring. No help. Any clues??? Thanks in advance.
oh yeah, theres no smell of gas or a sign of leaking and its only noticeable when I'm at 40mph (the gas needle moving, that is )
