My 205 seems suddenly seems to be losing accelleration. It?s an H reg so is not the quickest anyway but in the last week or so the accelleration seems to have all but dissappeared so that the car is almost undriveable. It?s ok when it?s up to 30 but it?s embarrassingly slow getting there and accellerating harder just revs the engine and it doesn?t go any faster.
A month or so ago an unnamed person, put diesel in the tank by mistake but this was cleared out and after a week of spluttering a bit it seemed back to normal for a couple of weeks. Could this be related or does the problem sound like it could be something else? Help anybody?
