Welcome to ZDriver! :006:

I have a 76 as well... it's a good year. :D

These cars don't have MAF's (mass air flow sensor) the have AFM's (air flow meter)... just to clarify. And yes, the AFM and TPS could be causing the problem, along with a clogged fuel injector, bad or corroded sensor connection, spark plug arc'ing / grounding, etc.

When you say you did a "complete tune up", what did you do?
