Check those leads, very easy to get them wrong on the 2-4-6 bank as they don't connect to the coil pack in a 2-4-6 order!

Right. Progress is halted on the ICV for now as I appear to have lost it  >:( >:( >:( >:( NO idea where I put it, finished cleaning it out last night and must have left it somewhere safe and very very clever to drain fully.

Also won't be getting anything done tonight as I'm out. But when I do get chance again, what is my best approach on the vac hoses? They all look fairly crusty and bodged over the years, but that doesn't necessarily mean they're leaking. So, without just assuming they're all duff, and buying a whole set of new pipes, what's the best route for looking for leaks?

Also I presume the all the vac pipes and hoses need to be pulled out the way to check the on the DIS pack? Nipped home in my dinnerhour (where I found I couldnt find the ICV) and I can just barely make out one lead on the DIS pack. That thing is impossible to see!!!  :'(

To check leads on dispac take off scuttle. if you need more access then remove plenum.

Re vac hoses make sure they're in the correct order by tracing them back from multirams using mark's excellent guide on ''V6 Vac Pipe Layout''.

HAHA!! You're not far off! Got a text off my sister a few mins ago, to ask if this old car part she found at home is ok to give to her hamster as a gnawing toy thing.  :D

Apparently it was inside a wood climate control panel, in the hallway.

I am happy to add this adventure to the list of things I shall never live down  ::)

Let this be a lesson to OOFers - don't store your ICVs inside a spare Climate Panel at 12.30 at night - they are prone to becoming lost!!

Next step, just had a brainwave...

Would the incorrect crank sensor (of no known history, as from a breakers) be cause for my woes??

Seem to recall a broke crank sensor will kill the car, but a failing one, or the wrong one will cause shaky running - does it extend to actually stopping the car idling?

Next Q - is there a way of knowing what CS my car is supposed to have?

Quite possible
Early 2.5`s were fitted with the Siemens CS

I'm sending Rob G a pack of cookies, now!  :y

Right, on the lookout for a Siemens Crank sensor then!  :)

I think there is only one type of crank sensor with square connector (early 2,5)  and two types with oval connector. You have propably the one with square connector so that's identification made easy :)

Just for reference, here;s my MAF sensor, which I think is supposed to give a good clue (though not always conclusive?) as to which Crank Sensor I need? (will check tonight which is fitted)

Hi, Diamond Black Geezer, I find this thead fascinating. Good luck in resolving it.

How long had it been standing and not run?

Was it running normally before?

Was it left outside in the weather all that time?

My Senators behaved similarly if left unused for more than a week. They had distributors right at the front of the bonnet, near the cheese cutter grill, and rain blowing in on them would cause symptons like the ones you describe. Omegas have their ignition electronics tucked away somewhere much dryer, but in time it may get damp and misbehave.

I actually find this fascinating, too. It's a problem to be resolved, that's all.  :y

1)  technically 1 year, for a matter of seconds, to test it actually ran after doing the cam cover gaskets. But as an everyday driver 7 years.
2)  Always ran perfectly, like a sewing machine. Even now it starts instantly, just doesn't idle.
3)  In car port. (Actually pretty well protected - rust no more than when she was laid up)

The ignition being rear of the engine, as you say, should leave it more protected than a Senny; however, the scuttle and wipers have been off for a while. (the usual direction of wind/rain does tend to leave the front of the car fairly dry, but not going to say you're definitely wrong. A damp/worn DIS pack is still possible)

If it ran a year ago plug led order, etc. must ne OK. I'd be tempted to put a hair dryer, or a hot air blower on warm air full blast above the coil pask and lead ends and dry things out. After a few hours it might run normally again.
