    Hi all,

    Got an annoying issue with my car. At idle, once warm, the engine is twitching and sending pulsing through the cabin that I can feel in the seat. I can see the engine twitch also. The RPM goes too 1100 on startup, then drops to 800 as normal. When the twitching occurs, I don't see the needle move at all - it stays perfectly on 800 RPM.

    I've changed the plugs (NGK iridiums) and it's no better. I've noticed when the engine is cold, and I pull away, it has a kangerooing hesitation around 2000 RPM. I think my PCV is fine.

    Car has 66k miles and is a facelift Octavia VRS 2L TSI.

    I think it could be carbon deposits in the inlet valves but at £30 for the seals, I'm reluctant to pull it all apart just to check.

    Any ideas are greatly appreciated, thanks!

    No replies in nearly 5 months? Surely someone has had something similar?

    I had P2105 error once or twice, but never an EML so I don't think the intake manifold has failed...
