I've had this problem in my 1991 Escort. Try this, replace your spark plug wires and/or check your pcv valve it could be clogged or not even connected to valve cover. if replacing your spark plugs and checking your PCV valve didn't work check for a vacum leak in your intake and exaust system

Can a damaged oil sensor cause a car to idle and drive rough?

It's extremely unlikely. Much more likely is rough running (usually due to engine management fault) causing a lack of oil pressure. Also, keep in mind that an excessively worn engine can cause both low or erratic oil pressure and rough running, but this will usually be accompanied by a knocking noise.
