'97 jgc, every now and then my gas gauge will suddenly drop to empty. It seems like this always happens on a hot day, while sitting at a stop light. Never seems to do it while riding down the road... The gauge will SLOWLY come back up to its correct reading. Most often, turning the jeep off and back on will correct it. Some sort of voltage drop at idle, maybe due to a bad ground? Voltage gauge looks ok. Also, sometimes, when hot, the starter will not turn at all, unless I release the key and try again. Could both of these problems be a bad ground? Unrelated? Any ideas?
