After not using my beast for a few months-winter, I had to replace a corroded
dist. Ever since, when driving, acceleration is fine, idle fine, but when
backing off acceleration and maintaining speed, it bucks and backfires like
it's running out of gas. Then I'll put my foot back in it or off and it's
fine until just trying to maintain a constant speed. Mechanics are saying
fuel pressure, vacuum leaks, but I don't see anything to indicate those
problems. I'm thinking maybe ESC sensor or module but not getting codes to
that affect. Also, I don't know where the module is located.
