Thought I updated this on Xmas eve but obviously not. Can't be bothered uploading the pics but basically took this out on Xmas eve and after a couple of miles it started misfiring badly, to the point I'm sure it was only firing on 2 cylinders. Parked up and left until today.
It started up fine gave it a quick blip of the throttle and seemed fine. Took the plunge and took it out a drive, got 30ft down the road and same thing happened but it is firing all cylinders just won't go above 3500 rpm and the noise coming through the air box is mental loud so something is causing to misfire, badly.
I thought it might be the coil pack so swapped that out 1st, still the same, changed the air flow meter just to rule that out and no change, changed the front 3 ht leads and plugs but yup still no change. I've had a good poke around and can't find any air leaks or anything obvious there. I can't change the rear plugs and leads because it's a manifold off job and I can't source a new gasket yet but that's the next job.
Also found an oil leak at the top but it's actually the oil cap seal it's leaking from so nothing too difficult there.
Left like that for the time being.
