coolant temp and idle control, as far as your fan would suspect the switch and resistor packs~

temp sensor...IAC (idle air control) would also toss a new TPS or throttle position sensor on it~

should be an ambient air temperature sensor as well, you computer will not figure it out until the throttle knows how rich or lean to make the mix under the prevailing conditions~
