147 - Hard to drive smoothly

So I've owned my 147 for a year or so now, its a 5 speed manual 2 litre petrol and it's a lovely machine, apart from one thing. It's really jerky coming on and off the throttle. So unless you're really delicate with your footwork it can be a rough ride, especially in traffic.

I've done a few things to try and rectify the problem, including the following

ECU and Throttle reset
Changed spark plugs (to NGK Iridium)
Changed air filter
Changed fuel filter
Greased up throttle cable and butterfly

And while all of these have made minor improvements, I've yet to find a silver bullet. Could it be the clutch? I know these run a dual-mass flywheel, but those are supposed to prevent these exact issues.

Any input is appreciated!

Sorry, got to ask...:
How did you change the fuel filter and grease the throttle cable?
It is fly-by-wire, so doesn't have a throttle cable and doesn't have a servicable fuel filter either.
Also doesn't have a dual-mass flywheel.

Hopefully you didn't pay someone to grease the throttle cable - if so I'd go back and have a word with them.

To your problem - I'd be checking for vacuum leaks, especially splits in the main intake pipe. And also check the engine mounts.

hard to say without having seen the car, but you could add engine mounts on the list.
