hey guys i have a 1.4 16v clio i am in a bit of a sticky situation. i left my car over night parked up and went bed woke up to go work in the morning and the car has an awful Judder/Shake and exhaust has a slight misfire. My first guess was spark plugs so i changed all 4 and its still the same i took it to a mechanic (which to me didnt seem to know what he was talking about) told me that my headgasket had gone? this was imposible as i checked the water and oil and every thing was fine. So now i turn to my fellow clio users and ask for help lol would any one possibly know why my car is shaking so heavily and turns off as theres not enough power ? HELPP!!!!
