Hi, this has started a couple of days ago: somewhat uneven idling, hesitation and stuttering at low rpm, particularly when in second gear at around 2500, some loss of power at low rpm as well. Performance at high rpm/gears seems normal as usual. I have changed the oil filter (looked ok anyway) and added some injector cleaner at no avail. So it is time for further investigation on this one. Any tips welcome as usual. Nikolas ps. 1.3 L TU2J2 motor, 1995 ralye S1
