For example, at the red light when idling and without touching the gas pedal, the engine in some cases starts «hunting», oscillating between the usual minimum rpm and an higher value like I was giving rpetitive pushes to the pedal, or, more frequently, the engine start keeping a quite high rpm (I estimate 2000 - 3000 rpm), VERY constant, before dropping back to normal.

Cold engines use higher fuel to air ratio and higher idle RPM, which is partly responsible for the increased volume.

An incorrect idle AFR can result in backfiring under close throttle high RPM operations of an engine, especially under load and deceleration.

The problem is that the output from the alternator varies dramatically - when the engine is running at high revs the voltage will be higher than at idle, for example.

You should first check for any vacuum leaks that would cause the engine to idle higher than normal.

A vacuum leak can cause an engine to idle high due to the excessive amount of air flow into the fuel injection system.

High idle should be corrected as it will cause harsh transmission engagement, waste fuel, and make it difficult to stop the car as the engine surges ahead.

What was offered as an option package and called the HELE system (High Emotion / Low Emission) allowed the engine to shut off while at extended idle and start again immediately upon driving.

When you accelerate, the engine RPM increases, and as you let off the gas, the RPM slowly returns to the normal idling speed with the help of the idle air control valve making the transition from a higher RPM back down to idle speed while adjusting the air / fuel ratio constantly to allow this to happen smoothly.

Once the car has warmed up the idle tends to be a bit on the rough side as if the engine is stuttering and sometimes when the clutch is pushed in and held in the rpm's will jump up and then go down low and it will finally settle in between the high and low point.
