Hi all, I started discussing the issue I'm having in the intro section of the forum but thought it better to start a new post in the correct section.
A few weeks back I'd started noticing a slight miss on idle, noticeable as a shake through the seat. I'd planned to get it looked at but a few days later whilst accelerating hard I got the flashing EML for 5 seconds or so and it ran badly as I nursed it home. This gave me P0304 and P1315 codes, took the car straight to Hoffmans in Henley who changed no 4 coil pack, much better but I can still notice this very slight miss on idle. I'm also getting an infrequent stutter whilst accelerating, normally happens at motorway speeds with the gearbox in something like 6th rather than a lower gear and hard acceleration. Hoffmans investigated further but couldn't find anything amiss and it wasn't giving any more codes.
Car has had a major service including plugs, mafs cleaned but the issue remains. On approx 40,000 miles.
Thanks to those who've given some advice in my intro post. Any other suggestions are welcome.
