Can someone throw some light on this problem please. My car is a 307 1.6s petrol manual 55 reg. At the weekend I was driving on the motorway and just approaching 95 mph, when all of a sudden the car developed a bad misfire, and the engine management light was flashing. Then after this, the misfire was there all the time and the management light was on permanent, and not flashing. It felt like it was running on 3 cylinders only. When I got it home and switched it off, then on again the light was off and the engine was fine, no misfire at all. My friend plugged his reader into it, and found code P1339, is this the crankshaft sensor or canshaft? is there a way to identify which it is, or if something else.
Regards
Pete
