How do I try peugeot coil 307 2002 gasoline 2.0i

You should start by relating simple tests such as the one performed (change of injectors) had a similar failure in a nissan quest and were the bike cables, in your case they would be the jumps or spark plug connectors

on the occasion, the spark plugs also fail and re -use them in case of not buying them and changing them to see the effect of the test

you could also put the scanner to see if there is a problem to see if there is a problem to see if there is a problem. Sensors' history because it could also be an intermittent failure of a sensor since these can advance time or delay it

I am not an expert but I hope it helps you a little luck

Thank you for answering in fact we think the same, change your position the injectors change the spark plugs for new ones, I managed to get a used coil I put it and this time the 2y3 cylinder worked, to which I asked to change it to me for another.
With which they also sent that fault which I saw something strange so I tried another coil of an Hyundai Accent year 2002 I did the connector and try to turn on in the first attempt and then only made counter -explocins, then I put the coil that was bought and by magic it turns up even in terms of the SCAner if it gave me several data of detonation, air sensor 1y2 cylinders failure, Cilin failure. 4, Catalitian malfunction.
Of which no sensor changed because when they measured them they were fine.
Finally, when he turned out evenly, he went back and deleted all the codes as a breakdown and did not give any code again today he has 3 days that he is not failing at all I hope he does not give me any failure and all a thousand thanks.

Original coil or China Nu more? China is shit, for all vehicles you have to have an eye that coil is one but inside it works like two, if only those discarding cylinders that it is a sensor problem because the 4 would come out in the same state if they are only those two then if it is a coil problem because the spark is very bad and does not burn the mixture well.
