Megane 1.6 16v K4m

Hello everyone I have problems with my megane, when it is regulated a little, like a cut in some of the coils. If someone suits any method of trying the coils of one, they told me to disconnect them from one but since the fault is minimal I do not think that change is noticed when disconnected. I await some answer, thanks .

Friend In the section of known mechanical problems, write the complete development for the K4M engine of Renault Ahy is the complete priest Checalo is long to explain.

Ok friend thanks I saw very good methods.

Hello, to prove if the fault is of a coil you will have to disconnect with the car regulating the 1 or 4 coil (anyone), if the car stops, then you have burned a coil of the other torque, that is, the coil 2 or 3, ok, burn ??? (Buy one and probá), if the car only under a little the rpm do the same but disconnecting the coil 2 or 3 with the car regulating, if the car stands burned a coil of 1 or 4 if the car does not stop your problem is not coil, possibly a sucking air, etc ...
