The best way is with a diagnostic machine, but the fluctuation of revolutions at idle is generally due to the IAC valve; in Fords it works at both high and low speeds, but clear up any doubts with a diagnostic test.

Hmm, you have an intermittent fault. The first thing you need to do is clear the fault codes. If another code appears, look for the circuit associated with that fault code; it's not always a sensor or an actuator.
