Gazza82's 1998 Alfa Romeo 156 TSpark 2.0

Actuator Reset

Before I did anything: this is how the idle was fluctuating and nearly stalling:


After the first Idle Actuator reset, the revs were too high: nearly 2000 rpm:

After the second reset, the revs were lower at around 1000 but the stalling came back:

So I tried a full ECU reset, clearing all the self-learn parameters:


Still wobbled a bit, but the revs were lower and slightly more stable. Left the car overnight and the next day the revs were much more stable, and I could feel a difference.

The car is now re-learning my driving habits (!).
