Update. Missing has been continuing despite a really good dose of Seafoam, did help a little. Yesterday while doing an oil change, thought I would have a really good look at the throttle body, noticed a bolt missing off the manifold. An hour later (lots to remove before you get to it) had the plenium off inc the throttle, talk about carboned up. Not a wonder the seafoam didn't do much, there were blocked holes and heavy carbon. Lots of scraping, poking, carb cleaner spraying later all clean, well as clean as I could get it. Reasembled and what a difference, one hell of a lot of performance and 90% of the miss gone, guess the seafoam might fix that. Thanks for all your suggestions, at least I know how to get the plugs out now.
