I gotta admit...I know more about my Camaro than I do my Cav. I gotta '93 Cavalier 2.2 and its all stock stuff. I noticed the other day my gas hand was on the 1/2 mark (which is how much gas was in it ) and all of a sudden, the hand jumped to the full mark and then back down to half again. It did this on a 20 mile drive every so often. It was pretty much a straight shot, so no big curves or anything. Could it be the fuel sending unit or just a glitch at the time. Any advice would be helpful. Thanks.
