Thanks for your answer yesterday re the plugs and oil. Went yard saleing the other day, and did the usual drive a mile, turn off the ignition, over and over. Probably drove a grand total of ten miles with 10 stops. At the end of the trip, I noticed I had supposedly gone from a full gas tank to nothing with the little warning lite for low fuel going on. I checked for a gas leak, nothing. Next morning, I start it up and it shows a full tank. Is it the gauge, or maybe an emissions thing? Thanks. BTW, I have been lucky, 128K miles, and it does not burn oil.

 

Check the tank sending unit connections for any problems. Barring that, probably a bad sender in the tank.
