I’m new to the site and glad I found something that is so specific to us V12 owners. I’m British and live in the South West of France, and by day fly another British iconic brand as a living. Hawker once made the Hurricane which helped save Britain during WW 2, but now the venerable HS125 keeps business executives warm and ‘comfy’ and bread on my table and a few cents in my pockets so I can pump even more CO2 into the atmosphere on my days off by thrashing around in my V12. This brings me nicely onto the reason for this post.
I bought yesterday, a beautiful Daimler Double Six, otherwise known over ‘the pond’ as a Vanden Plas. I drove it for the first time the 350kms from the showroom to my house and I noticed on arriving that even though it had a good workout, at idle, it tends to slightly miss and judder as if one or two of the 12 are not working all the time. I had new spark plugs fitted before leaving the showroom so these are out of the frame. And yes, they did replace pots 1 and 2 (underneath the air con unit) but it still I have this slight hesitation and missing. Any basic ideas before I take it to the experts?? I am thinking HT leads, vacuum problems, maybe it’s running a bit lean (the old plugs were a bit white), coil problems, anything I can suggest to the expert?
Thanks for your suggestions!!!
