I think this is all very interesting. OddSox - I'm still not sure what you mean by the idle being "not smooth". Are we talking about mechanical vibration that you can physically feel when inside the car? Or is there something not smooth about the sound the engine makes? Or something else?

I'm wondering if there could be a below-par engine mount. Perhaps you could post a video?

Thank you Ron. Are any other adjustments or changes required when fitting the VVC inlet manifold? Is the reason for fitting it to obtain better performance?

Hi Simon, the main reason for fitting a vvc manifold is that it's aluminium, rather than the plastic oem which tends to leak, causing that well known issue with the 1.8.
The vvc also is bigger in plenum volume allowing more air. After fitting, the ecu needs to adjust during initial running, and the 5 presses of the accelerator pedal helps with this. Better performance? Probably a placebo effect, but throttle response seems a lot crisper, other than that, no performance increase.
