Yes I think that ignition was definately causing the huge misfiring and
rough running but there had to be a reason for the general degredation of
the condition of plugs 5 and 6 which led to the ignition system not keeping
up.
I'm running NGK iridium plugs B-something-6-something number.
I agree about the condition of the filters and given that my whole car had a
recent rebuild and we discovered a fair amount of crap coming out of the
tank - I think my filter will need a change now too.

Hi, Glenn
Glad you seem to have got the problem sorted. As Graham Stretch said in
one of the posts, 90+% of PI problems are not PI system related - but mostly
ignition or other. Once the system is set up, it rarely goes 'off tune.'
Don't know what plugs you use but IMHO, the best on PI's are NGK. I use
BP6ES because they've always had excellent anti-fouling properties. What
Graham also pointed out is the critical need to ensure you keep the main
fuel filter clean. A cruddy tank will soon restrict flow through the media.
I change my filter half way through each summer Key thing here, is to keep
the tank full if the car is likely to be out of use for a while as unleaded
(in the UK anyway) quickly seems to lose its volatility.
