The flashing EML tells you that it's miss-firing as the only other time that it flashes (in my experience) is during immobiliser faults in which case it wouldn't start.

My recent faulty ECU (when it was on its way out) caused the EML to flash intermittantly, before flashing rapidly (along with the TC and spanner light), with a distinct lack of power, cutting out etc, before eventually not starting at all.
Oil / water in the plug wells in my experience caused a misfire, but displayed a continous EML.

Interesting as misfires on my 3.2's have usually made the EML flash and a 030x code to be raised, only if it's a very mild misfire has the EML stayed off.

Or if the cats are getting grumpy ;)

Obviously without any codes presented, there's actually very little to go on ;)

Ok chaps, I will start with the Coils and Plugs. Never done these on a 3.2 ( only a 96 2.5 CD), is it quite straightforward  ?, but I expect it to be a bit fiddly.

Good guide for it all here:

Plus something to watch when removing coil packs:

Another tip, for the injector rail electric plugs I use parrot grips to push the springs in to pull the connectors off, as they are painful to try and remove with your own fingertips.

P.S remember to remove plenum chamber thingy connecter at top right of plenum, as I pulled my plenum back with it still connected and broke it.

Why do you need to unplug the injectors ???

You don't even need to undo the fuel lines.

If it has been disturbed, has the vacuum pipe to the brake servo been checked for leaks at either end?

Was thinking of the cam cover gasket process, but it wouldn't go that far now that I think on it.

Just unplug the single plug* that sits on the rear lift point and fold the whole manifold over to the scuttle above the brake booster.

*I don't recall ever unplugging the injector master plug for this purpose, but don't have an Omega to test it on. Certainly, you can leave the fuel pipes attached.

For cam covers you only need to shift it about half an inch to get the camcover off.  :y
