So i have a bit of a reccuring problem with my 1.7DTi astra with hesitation and misfire etc. Been trying everything to solve it and have never found a solution.
Recently it has been behaving fairly well not causing me any trouble at all until... i fueled up again at my usual filling station... Tesco... ever since its driven like a pile of poo again. I have now made a link between tesco fuel and my problems as the previous 2 fill ups were at asda as i was local at the time and the fuel is about 3p/l cheaper and i had very little trouble from the car.
Any thoughts on this?
