MPG (not good...)

Ours is still returning 250 miles to the tank following the service (oil, plugs & 02 sensor).

Have you actually worked out the mpg?
You have a 10 gallon fuel tank. When you fill up you probably have at least a gallon, probably 2 left in the tank so you're getting at least 28mpg, probably more. That's about normal for combined road use.

Well it's not carbed, so not sure what you are suggesting. I chuck some Wynn's Hydraulic Lifter treatment in the 710 filler from time to time though.

I read somewhere, thought it was here but may have been on the OC forum, that Wynns carb cleaner sprayed in to the air intake can help to clear out all sorts of gunk. I seem to recall this was suggested as a cure for rough / low idling as I was having that problem at the time. I never did it as I couldn't work out exactly where to spray the stuff. Changed the plugs and leads, and adjusted the base idle instead and that sorted it.

I've done this and it helped our rough idle. I've got a link on my PC at home which shows you how to do it - when I get home i'll dig it out and post the link.

That would be great. Thanks.
