1998 SW2 with a Bad Thermostat

Thermostat stuck partially open and engine running cool. The Coolant Temperature Sensor is working correctly.
Only 178 degrees Fahrenheit caused the Air:Fuel ratio to be below optimum 14.7:1.

(We know this, because when we replaced the Thermostat, the Temp was steady at 195 Deg. F and the A/F went to 14.7:1)
