Any body help here with a strange judder coming from my chicks puma, it only does it when you slow down using the gears, say from third too second, and when the car slows it starts to judder quite bad, its as if its gony stall or cut out, but when u give it a little bit of gas it goes as if theres nothing wrong, could this be as little as a fuel filter or something, the cars been of the road for about 8 months, any help apreciated
