Strange Fuel Reading: Help? (2000 3.0 Ranger)
I recently purchased a 2000 3.0 Ranger with an automatic transmission. The truck and everything works well and runs out nicely for a car with 140,000 miles. The only strange thing is the gas gauge seems to move back and forth a lot. I filled it up to 3/4 of a tank today, and a mile down the road I hit a light and sat there for a few seconds, and suddenly the gauge dropped to half tank (I freaked out) but then when I put my foot in it and got up to highway speed, it shot back up to 3/4 again. Seems really strange. It would be really nice to know exactly how much gas I have since this thing likes to move back and forth so much. Any suggestions? My natural assumption is that the gas tank sensor is a little off but I'm not sure.
Also, the truck is leaving behind a very tiny leak of oil whenever I park it. I looked underneath it and it looked like it was coming from the drain plug, but i tried tightening it and nothing. How do I go about diagnosing where the trouble spot is?
Any help would be very useful,
