Hi guys, I looked at the Punto of my brother-in-law yesterday. The car is a Punto of 2002. Machine with 44 kW (60hp). When it is cold, it runs slightly unround when it is idle….as if a cylinder is not running fully. In addition, in the first 30 seconds a bad gas acceptance occurs. Later it adopts normal gas. In addition, the car is slightly jerking when it accelerates. The acceleration is not constant, but there is a power hole in a certain Rottazhl (so 2000 to 2500 rpm I estimate). If it then gets quite warm, the leak hole is still hard to remember, but is still there. I have read out error code “D 0: 0.” . The error memory I have deleted. The error memory does not appear again even after longer usage time. The car has 13.000 km down (that is no typo, it really has so little down). New spark plugs are in, all filters are new and the oil is also new. Does anyone have a tip from you?
