As usual, check for codes (even if the CEL is off).

I'm thinking either faulty Idle Speed Control valve, possibly vacuum leak. Check the TSRM for testing procedure of the ISC, and listen around the engine bay for vacuum leaks with the engine running. I believe an out of adjustment TPS may also cause this issue, testing and alignment procedures are also in the TSRM.

Yep possibly any of the above, but also could be a fule pressure issue if it used to be worse on low fuel. Have you changed the fuel filter/checked fuel pressure? Could be a blocked filter with sediment from running low or failing pump/resistor.
