My question is can valve stems be bad and not produce a correct reading at first attempt? ...
Valve stems certainly can be "bad"! And they are very easy (and usually inexpensively) replaced at most any shop or tire store.
Dirt, gunk, sludge or whatever can muck up a valve stem, and it is usually easier and quicker to just replace it. If there is a piece of dirt in the valve stem, it could be jamming randomly the movement of the valve, explaining weird psi readings.
New sensors are part of the valve stem now. Cost 20 some dollars each, depending where you buy them.
