I've been following this and have no mechanical sounding to comment really.
Is this not a timing issue?

A shaky idle suggests the leads are mismatched!
I would check your coil packs are connected in the correct order as it is SO easy to get two mixed up (or worse).
My guess is you may have muddled two (or more) of the leads on the coil packs because they as so bloomin hard to get at.
I ended up removing the manifold so I could get at the coils, changed them all and found my mate had mixed two up. Once they were done right she ran sweet as.
When I initially picked her up, she ran like a bag of nails, but she started and drove! Mice had chewed through 3 of the leads...
Anyway, I would deffo check the numbers again, just to be sure.
Failing that, you should get the fuel values checked out as she could need a re-trim. But check out the "free to check" stuff yourself 1st.

It is a gems. This problem described could be caused by a cracked flex plate.
Check the old crank sensor for any damage.

Each coil pack contains two coils, pack 1 feeds 2-3-5-8. Pack 2 feeds 1-6-4-7. The system works on the lost spark principle. Two plugs on each coil are fired at the same time. One when a cylinder is on compression and the other when the cylinder is exhausting. So for instance if cylinder 2 is on compression and cylinder 3 is on exhaust, coil pack 1 will fire the plugs on cylinders 2 and 3. And so on and so forth. If the leads are interchanged this will not happen and rough running will take place. Cylinder locations are Left bank 1-3-5-7. Right bank 2-4-6-8 Left being left side of engine as viewed from drivers seat. Number one cylinder is left side of engine at front or crank pulley end.
He says it's Motronic.

err i think i may see your problem..
the cylinder numbers are low numbers front, high numbers by the firewall. odd right, even left..
getting the leads ass backwards will make it run like it **** for sure !!

That's what I was thinking! Lets hope he's nailed it, good call Adam. Beat me to it
I learned from experience
Just picked it up from the MOT centre. Passed, but temperature gauge when straight to red on the way home. Pulled over, steam everywhere, opened coolant filler cap and the water exploded out. Filled it with 5 litres of water, locked it and left it for the night.
Head gaskets maybe damaged again?

In post #84 you say it was running fine before you changed head gaskets. Why did you change them? You obviously have little idea what you are doing.
