ive got a customers 2004 pilot has a p0301 code. cyl 1 miss fire. i have 5 plus years dealer experience to start off with. i cant find the issue with this one. swapped and changed 3 coil packs (one was falling apart and one fixed a miss on cyl 4) but cyl 1 is still missing. have further done valve adj found a few snug valve but not tight enough to cause a misfire swapped the plugs with known good ones have 165 to 175 compression across all leak down test was only leaking 8-10 % down which is great swapped cyl 1 and 2 fuel injector and missfire didnt change and the engine is in time. any ideas or any experience with this before? any help would be great thank

 

 

thats what im kinda leaning to it seems to only miss under a load i wish i could get it to do it when its idling so i could move some wires around.

 

 

not much left pretty much tried everything i can think of it makes sense when im driving it under load maybe the engine shifts alittle and pulls the wire. will try first thing in the morning thanks for ypur opinion i really aprecciate it
