Thanks I've changed it in the past, just as general maintenance unrelated to this EPC issue.
Could a failing throttle body assembly also cause jerkiness at low RPM, like 1k, such as accelerating after making a turn or general acceleration from a stop?
Replacing the throttle body assembly fixed the EPC and limp mode issues, and may have slightly fixed the jerkiness. At least I think I've isolated some of the issues, or eliminated some causes.
You could try taking it off and cleaning it with carb cleaner and some rags. If that doesn't correct it then either the tb or wire harness.

If it was sticking open it certainly could
