Right so today I did the compression test. Did it on a hot engine. My results were

#1: dry: 12.5bar. Wet. 13.5
#2: dry: 13bar. Wet. 14.5
#3: dry:13bar. Wet. 14.5
#4: dry:13bar. Wet. 14.5
#5: dry:13bar. Wet. 15


So compression Although a little off but they are on the top limit. However when I pulled cylinder one plug out it was oily and the piston was a shiny black rather than a Matt colour. They are all black from carbon but #1 is shiny which may explain my misfire. But I’m not sure what it could be though. I did clean the earthing point for the coils just to see if anything improves which I doubt very much but remember this seems to happen when the car is hot. So His also happen on lpg so it’s extremely unlikely both injectors would fail and you can hear the lpg injector click on and off anyways.
