Yeah tried a different one on the car but no different.
Revved it up in neutral today before it even got up to temp and the missfire still came in at 5k, so looks like I was wrong regarding temps being an issue, however booted fine in second gear when I took it out?!
Msd plug kit is sat at the post office depot waiting for me so will grab it tomorrow and hope the crank sensor cures it!
