I have an 02 GP that I purchased new and now have 150,000 miles on her. A few weeks ago i filled her up with gas and since then the gas gauge needle fluxuates constantly reading anywhere from full to almost empty regardless of how much gas is in the tank. I keep a close eye on the odometer to determine how many miles I have driven since filling the tank to prevent from having to walk. Can anyone tell me what I need to do to correct this situation? Thanks in advance. Bill
