over-run when ignition turned off
my car has developed a slightly embarrassing trait. when i turn it off the engine continues for one last gasp ending with a noticeable judder as it finally dies.
does anyone know what causes this and how i can fix it. i have a thick skin but for some reason i find this new behaviour rather embarrassing.
it makes my lovely car sound like an old banger, and i can't be having that!
many thanks in advance, as always, for all your help.
