Hard to diagnose just by videos but can hear it. What parts stores do you have around? Keep after the fuel issue. In mean time pull the module from the distributor and have it tested. It's missing bad, and is indicative of the module high side going out.

On a fuel injected car what you have imitates a bad cam sensor. In the emission system you have, the distributor fills in as the cam sensor.

You can't effectively diagnose bad transmission operation if the engine is not up to task. So we first need to get engine right and go from there.
