The speed sensors will not fix it. This is something that these cars will do in hot weather. The instrument cluster need to be removed and the contacts from the printed circuit to the connector need to be cleaned. Over time they will lose contact and affect the fuel gauge or speedometer. You may have to replace the speedo cluster. Sometimes if you hit the dash just above the fuel gauge it will start working too. Been there done that, fixed mine as the printed circuit was coming apart at the harness connector.

The tiny electric motors that move the needles on the cluster are prone to failing. New sets of them are relartively cheap on E-Bay. Takes patience and some skill to change them.

Found the problem with the speedometer on my Buick. When you use the magnet to fix the gas gauge, will can and may affect your speedo. So use the magnet trick on it as well. Appears that the manufacturer didn't think about the needles being able to swing past the magnet they have set up in the gauges. Should have put a stop pin on the gauges.
