Poorly Cerb - Won't start/running very rough
Discussion
Was running brilliantly but then the Cerb started dropping to 7 cylinders/missing on the way to work Fri, same on the way home, but got worse.. Was fine when first started, and cleared briefly a few times. Pulled lead/coil connectors, tried it again this morning and it was fine for the first few mins..
Left it parked up came to move it and it died, realised I'd run it out of fuel (yes whoops!) Brimmed it and it was running a tiny bit better, it would take some throttle.. Although it was popping and banging out of character. Now parked up at home went to drive it and it won't start, just spinning over, give it some throttle and it splutters into very rough life but you get smoke from the top of the engine which stinks of fuel, but basically won't run.
I'd initially thought plugs/leads/coils (cheap enough to throw at it, and it is probably due them tbh), due to missing under load. Now I'm a little concerned it may be a bit more involved due to the fuel flavoured smoke..

I have same problems, and I'm doing the same parts, will compare notes later then! My ECU was giving no faults apart from AFR on all cylinders, which points in all directions. Mines due coils, so starting with ignition, then balancing TPots and hopefully that just leaves the lambdas. You really do need the software to check and set up things properly.
I had a bit of a misfire a few months ago and did a comp test. These are the results I got, have no idea if good, bad or indifferent? Turned out only to be a plug lead not home.

They are poor, over 15% variance, but considering the state of the followers and more importantly the corroded bores, not that bad.
