: solve Motor stops is in good condition, and you pass to the other, when you disconnect one and the vehicle does not stop there is the problem, now these coils change their appears, but if you do not want to do it and just want to change one of the two coils that when disconnected with the car walking does not stop the vehicle, take out one of these and put it in the place of which if it stops the vehicle, Test again, in which the vehicle does not stop is replaced and now.

Hello, how are good, it looks with respect to the topic theme in the k4m the easiest way to detect it is to disconnect the injectors one at the same time the coil that is fine, the one of the coil in short fails does not fail to verify if it really is the coil it is changed with the cylinder 2.

Hello, allow me to tell you that the best test would be that of the injectors, because the K4M engine uses coils connected in series.
And sometimes the failure of one transmits to the other even in good condition devoted to its connection, the number is connected in series with number four
and the number two works in conjunction with the three
if any of them were in an open circuit is certain that its partner will also fail and it will not be damaged it is also damaged.
Another observation The coils in the K4M engine are very delicate and being disconnected and connecting them sometimes damages them.
Another solution that we have is the scanner that can tell you that cylinder has badly burned
and serves this information for a good and precise diagnosis bye that are well.

Also the coils used by the K4M engine can be removed by one with the ESEIDED engine, with a coil and a cable to put it on the ground with the other end of the cable, pass it from the coil through the cachinvo and around the coil if you observe and listen to the spark it means that the coil has a leak and is to be damaged this out of the minimum instability in the minimum, eye does not take it out of the connector. It works, you must get it complete with the connector plugged in and do the test.
