But I was wondering how they work. If a graphite POT is in them,
then Hell!, they'd wear out fairly quickly moving back and forth
with each throttle movement - Gozillions of times a year!

Well in the 2-3k range it just bogged down now it is doing the violent stuff yours is doing. It was fine untill I unplugged the O2 sensor and plugged it back in. When It jerks the check engine light comes one but then turns itself off.. its really wierd. I have a rebuilt ECU.. I'm probably going to change the tps and o2 sensor and see if that helps. Or just take it to the dealership..
