My Buick Lesabar Misses while climbing hills. There is no engine light to direct me to the problem. Just a shot in the dark but could it be a VSS or TPS.

This sounds more like secondary ignition breakdown; i.e. coils, wires or plugs

Yup, secondary ignition. Look around the coil terminals, where the metal stud comes out of the coil housing. If there is a black residue, that coil is likely bad.
