Has the SEL(Service Engine Soon) light ever come on? You might have some codes stored in the computer that might tell us something.

When my "Speedometer went Bezerk" once. It was due to the fact that my VSS(Vehicle Speed Sensor) failed. Cruise Control and the Transmision O/D was also effected.

I'm not sure what is causing your engine to stall/backfire when hot. But I would get this car scanned for codes.

Have you had a tune-up recently? Is there a vacuum leak?
