Just a quick one, how would I know if one of my spark plugs is on its way out?
I'm getting some juddering in acceleration but only in low rpm.
Or could this be my M.A.F?

You'd get a misfire and it would usually be more pronounced when under load.

Are you getting this issue when keeping constant throttle? Or is it as you're accelerating?

I'm thinking it could be the disa valve.

Could also be a coil pack? Had one that was failing on mine, no fault light just occasional judder. Replaced plugs and packs for £120, all now OK.

(should have done it at 100k)
