Two things come to mind. The first is the ignition control module located behind the distributor ( on the back of the distributor) ( its a little rectangular shaped plastic slim box attached with two 5.5 mm screws. Take it off and get it tested at auto zone or another parts store. The other thing that comes to mind is the temperature control sensor located behind the top radiator hose. Its kind of hidden. Disconnect negative battery terminal, remove top radiator hose (only if the engine is cool so you don't burn yourself). Remove thermostat housing, remove connecting wire from top of sensor, use 1 1/8th deep well socket to remove sensor. Put thread tape on new sensor, and reinstall.
Good Luck
