Problems with a 307 SW 1.6

Hello everyone I need a acesitory I have a problem in 307 SW 1.6 year 2007 the problem is that when I start the engine, it locks and then part and when walking it works in 3 cylinders, the distribution is to see as precaution to see if it is outdated and nothing taba correct I have cleaned all the sensors and neither did the other test Super good and does not work, can it be the coil or is it an internal engine problem?

If you are in three cylinders, the most caused thing is that it is the coil in Peugeot they fail to disregard 406 2006 has the same problem and 206 and all these models devised to the unique coil that they have, if it is the 4 bolts it is not so expensive but if it is the one of three bolts you will get very expensive.

Another question Carman looks at the Pruba of the coil I did it with some spark plug cable Accelerating it would be pure noises this at least it is not accelerates well but it sounds like the sparkle is missing in the cylinders of this one has 980000km there are so that you clears me some doubts and beforehand thank you thank you

The most egurur is that you have the defective coil, since they are coils that work for lost spark, this is to say that it gives two simultaneous sparks in two cylinders, the coil is two phases one is giving you spark and the other does not Negative signs of the phase of the coil, if when you start in a signal cable you have nothing or a fixed signal (xq have to be negative pulses) you can have the wiring or failing the engine module.
all the best

These cars if I am not mistake
