Been having issues with the 1.4L Multiair having an "arrythmia" after pushing the car hard. Upon...
I noticed the idle to miss a beat, or have a very small arrythmia when the car was new, three years ago. Now at 30000 km and 3 years the problem is very noticeable, the idle rythm changes, missing a spark perhaps, and vibrations are very clear.
Any experience here on the possible issue...
