Gas Gauge \"Jumps\" For No Reason Anyone know what can cause this? I posted a while back about the gauge being off but now while sitting at a few lights I just saw the gauge go nuts. Went from Full to 3/4 in one or two jumps and then back again. Any ideas how to fix this? How much? I will be talking to Chuck again on Monday but until then, wanted to hear if anyone else had this problem. THANKING YOU ALL IN ADVANCE!
