The 71 FI system is about the best year, and everything there is 
fixable, just don't start by randomly replacing suspected parts, as 
that is the most expensive and least rewarding way to go.

Your problem is NOT the TVS or the AAR.

It is possible that there is a problem with the distributor FI 
trigger points. You could take them out and clean them (DON'T FILE 
THEM!!!) or send me the whole distributor for a checkup and rebuild 
if necessary.  That costs $55, plus the cost of any major parts.

I would check the hose to the pressure sensor and make sure it is 
connnected at both ends, then check the system voltage. It should be 
14.1-14.4 V measured at the battery with the engine warm and running 
at medium rpm. If the voltage is below 13.5 V, replace the voltage 
regulator with a Bosch 30-019.

I have any part here that you might need to get this running, and it 
will be a LOT cheaper (and more reliable in the long run) than any 
carb conversion.
