P0720=Electronic transmission control diagnostic trouble code memory
P0500=Vehicle speed sensor signal implausible.
P0173=Fuel trim malfunction.(Leaking intake, injectors, or pressure regulator diaphragm
P0170=Fuel trim malfunction. Same as above.
P0100=MAF circuit malfunction

Sounds like a defective computer or a loose connector.
