Have got a small diagnostics kit,gives me P303 cylinder 3 misfire.My car currently runs with a misfire and when driving the car engine light would randomly come on and that's when the car would run really really loud,misfiring much more and on the line of stalling.I then turn off the ignition and turn it back on 1minute after and the engine light is gone and car is running fine again.I have changed the ignition coil and spark plugs and still misfiring and engine light appears.
