Hey, help me. Peugeot 307 jerks after firing on a cold engine, in addition, an antipolution fault error pops up. The computer shows the ignition coil. I would like to add that the coil was replaced (used fact) and the lack of improvement, maybe for two days it only stopped jerking, the error went out shortly after it showed up, then the revolutions started to wave and the ignition fell out. The coil has been replaced with the old one and continues to tug. I learned that they can also be pusher glasses that have a problem with the oil and therefore tears. The oil was changed to 10w40 because it was previously pulls on. Checking the concentration on the pistons showed that it varied between 13.5 on two cylinders to 13.7 and 13.8 on the other two. Help to buy a new coil and candles or what to do?
