My Renualt Megane "p Reg" Has All Of A Sudden From Today Got A Terrible Vibration Noise And A Little Loss Of Power, I Drove Through A Puddle Today But Not Sure If That I,ve Applied Some Water Repellant To The Engine. When Diving Slow In 2nd Gear The Car Shakes And Driving At 30 Mph In 4th Gear Sounds Awful The Car Sounds Like A Tractor. What Is Wrong?
