Any broken or malfunctioning ones. If none are doing anything abnormal, leave them alone.

water temp sensor @thermostat housing, easy to check with a multimeter and if not working correctly will affect MPG

First off, hows your gas mileage? 10-15 is normal, 16 and above is very very good.

Crankshaft Position Sensor....if inaccurate, it may say timing is advanced or retarded and adjust fuel accordingly.
