Yea, I understand it has 300k on it but low psi means fuel/air is getting by which could be causing a leaner condition when off the throttle.
Other than that, its timing related. If you have advanced the timing at the distributor, set it back to "0" stock with the EST line disconnected. If you haven't touched it, advance it 4 degrees and see what happens.

A handy way to probe your wires without puncturing the insulation is to strip about 3 or 4 inches of a piece of scrap wire and seperate out a couple or strands, twist those and then unplug the throttle position sensor and place them in the terminals and then fold the excess wire back towards the harness and plug the connector back in. Some say this will spread the terminals but if you only use a couple strands it shouldn't and it is a simple way of probing without puncturing the harness.
