Definately a fuel problem, car started, lumpy and rough as ****. Disconnected cylinder wires separately and the only one which didn't make any difference was Cylinder 3, it took a lot longer for the engine to stall. Started it back up and kept revs at 2000rpm, sprayed some lighter fluid (naughty I know) and the engine purred like a kitten until I released the throttle. This time though it popped up an error code (P0269)... FINALLY!! Cylinder 3 is out of balance, checked the resistance on the injector and voltage on the wiring again and all is good so either injector 3 is fucked or clogged up. I have always used BP Ultimate so can't be clogged up but you never know. Is there a really good injector cleaner I could use before I go down the replacement side of things as getting injectors out of my engine is going to be a pig as I'll have to take wiring loom and rocker cover off.
