Temperature guage was dead centre. Then suddenly I lost one cylinder and the engine began to shudder. But still had to drive quite a bit in the jam before I could bring her home.Later in the evening I checked all my spark plugs and they were all a healthy brown. Sanded them a little with fine grain sandpaper and put them back but still same problem. Also I notice a sweet smelling gas in the air when the engine was running. Can't tell if it's unspent petrol though. So what could it be guys? Lost a coil? Clogged an injector? Fuel filter dirty? My engine is a M50TU.HELP!!! CNY around the corner and no car to use!</p></blockquote><p></p>
