hi, this is my first post, ive had a look through the problem pages but cant find anything relating to my problem. i have a 52 plate Saxo VTR which i have owned for about 3 months, i can do basics on cars but no wizard. recently changed cam belt, tensioner, waterpump, spark plugs, coolant, temp sensor (dont know if all that info helps) and the car has been fine for over a month now. yesterday on the way home from work, i stopped at traffic lights, as i pulled off my car went from silent to having a knocking/rattley sound and when accelerating the car is misfiring (i think) and has no power. at first i thought it was the coilpack as my 306 had a loss of power when that went but no noises, changed the coilpack today but still no difference. the car makes the noise under load or not. it has also started stalling when pressing the clutch in, any help would be greatly appreciated if anyone could shed some light on the situation. thanks.

check the timing hasn't slipped could be the reason for loss of power and the knocking if the valves are just touching the piston
