Superb, thanks.
You've done very similar to me. Mine has always done it, so because I was running a tune I had my plugs changed early, but the throbbing seemed to be stronger afterwards. However, the weekend before I'd fitted M3 tranny bushes, so it's possible that's the reason that I'm feeling it more now - though I didn't notice until a week later after the new plugs were fitted.
I then tried fuel system cleaner (2 bottles in 2 consecutive tanks) and no change.
Then most recently I had the intake ports walnut shell blasted and still no change.
It's possible that my issue got worse when the plugs were done because a coil got damaged, but I'm not getting any misfires, I don't think. (Not 100% sure how to tell, but the car isn't throwing up any lights and it runs perfectly at any speed other than idle, so I assume it's not a misfire.)
As such, I'd be really interested to know what you find.
Thanks for your feedback so far, as well.
