Misfire on V6
My car has developed a misfire this morning. Particularly bad timing as it was due to be shown in Bristol tomorrow morning.
It was fine this morning for the first 5 miles, then after a left-hand bend it starting to run rough and judder. It's also idling badly. I am fairly sure it is down a cylinder. Curiously enough later in the day it ran better and the first 7 miles of the journey home were ok, but then after a left-hand bend the fault reappeared. The connection with the left hand bend could be purely a coincidence of course and it may be relevant if the engine is hot or cold.
Of more likely cause, I cleaned the engine bay 2 days ago. It ran fine all yesterday though.
I've looked for water/damp and have sprayed WD40 all over the place to try to disperse any remaining water. I suspect a coil-pack.
So any suggestions for diagnostics before I submit to the dealer?
