I've heard of this knock sensor, but never dealt with one....

Could this also be the carbon canister causing too much vacuum on the tank? Try popping your gas filler cap when she is misbehaving and see if a quick rev will make it behave. It tends to work on some older YJ's all the time... Give it a shot....
