hello, I also want to dare to ask here, since a few days my engine (y22xe) mostly only runs on 3 cylinders. working in cold condition all 4 cylinders, as soon as I have driven 3-5km sets off a cylinder and again, when I play something with the gas pedal he works again for a time. when driving you notice the failure and the again working of the cylinder by acceleration or slip reduction. yesterday I installed new candles after I tested the compression t had (all 4 cylinders were 14.4 to 14.6 bar). Before about 7000 km the water pump and the timing belt was renewed. best thanks for the effort you all make here, I find great and successful to read here!!
