I have 1990 olds cutlass supreme that has been having idling problems. It won’t idle at all now, once the engine get warm. It is a 3.1 engine. Do you think it could be a sensor problem?

    You may want to make sure there are no codes present as well: http://www.freeautomechanic.com/diagnostictroblecodes5.html
