I've been consulting my Haynes Manual. It lists fault codes for "Fenix 5.2 system," "Motronic 4.3 system," and "LH3.2-Jetronic system." Now what chart should I be referring to?

I was finally able to clear the codes in the A module. The A-6 2-1-4 reappeared so I cleaned up the connector which had that green build-up on the contacts.

I do not have an SRS light on as you suggested. I can live with the environmental snags, but the sudden stalling and engine "bucking" I want to solve. Do you think I should be concerned about the fuel pressure regulator? When I disconnect the vacuum line, there's no effect on the engine performance. No fuel in the vacuum line. BTW, that engine "bucking" usually happens when accelerating and in third gear. The other stalling scenario is when I'm stopped, I barely touch the gas pedal and she conks out.

Thanks for helping out.
