Finally some real progress made! The car is now idling, turns out dickhead here was counting the fuses from the wrong side so when I checked fuse 15 it wasn't actually 15! lol, 15 was blown, ISV started working again, hey presto! Idling again! Now though, I'm back to having juddering around 2500-4000 RPM :/ however, this time, with the Crank Sensor replaced and everything else I have done to the engine, I'm pretty sure its down to the crappy HT leads fitted by the previous owner! Hopefully a mate will pop down in the next few days to let me try the leads from his car so I know for sure before buying a set for myself
I also fitted my Joey Modded CL headlights I kept from my old MK3.
