21 is TPS high. www.avigex.ca/xport/dtc21.jpg TPS is a variable resistor and can be tested easily: key off, disconnect the plug and test resistance between sensor connector B and C: initial value should be a few hundred ohms, adn then as someone slowly depress throttle, resitance should increase steadily to a high value..probably 5k or 10k ohms. Key point is you must have a steadily increasing value, not a sharp jump which would indicate prokec resistance track. Also possible, loss of contact at some points, specially at "normal" throttle position.
Maf is more complicated to test...

but obviously, at some point, it procured some "out of range" value which might also relate to your previously reported problems with stalling..
