When you changed the stepper motor, did you change the spacer between bosch unit and manifold? Have you got a manifold to head leak when cold causing a weak mixture? Have you checked your plugs to see what colour they are?
When you change the coolant temp sensor, ALWAYS use a Fiat item, not an aftermarket one as they are no good. Airflow sensor maybe faulty allowing a lean or over rich mixture[check plugs].

Why dont you have the emissions checked and a diagnostic done?
Emissions were OK since last time I measured them. I also checked sparkplugs, and they matche those in Haynes manual with good condition - slightly brown/grey deposits. But somehow I think this Tipo is caching his age, the engine is not as it used to be. Engine strenght is fading. It seems like some of it's horse powers were being taken away. I tried Polo 1.4 Classicc 1999 with less horse power (aprox. 60 HP), and engine simply has more strenght then mine.
