strange case of ignition failure! :EITHER

Hello everyone how! Well, I have a strange case in a Nissan Platina (I bone the same engine of the Renault Clio) that has a cylinder failure in the piston 1 (that says the scanner (P0301) I have changed the coil and the spark plug of the cylinder one, I traveled 50 kms and surprise! The fault remains the same!

How about Carlos. From what you say it looks like compression failure in No. 1. Check the compression, and if it is correct, check the packaging of the admission collector that may have a small air intake (both the 4 torics of the collector to butt, and the large one of the butterfly box). Have luck ...

Thank you very much my estimate! We already reviewed the compression and it is excellent, I found that the problem was in a line of the coil wiring, fortunately they supported me with an oscilloscope and we detected that the spark signal did not always arrive, we found the exact point of the false contact, we made the corresponding addition and voila! like new! And the satisfied customer!
I hope this case serves as a reference to future difficulties of the others in the forum
