Ordered a new fuel filter. Experiencing some shaking on idling and it's becoming hard to start when cold. Definitely not spark plugs as I fitted some Denso's before Summer. Should be with me next week.
With those symptoms I'd check the Idle Control Valve as it might need a clean rather than fuel filter.
edit:
Another thought might be Tumble Valves getting lazy and about to act up possibly (as just saw you're driving a Hawk), though would still check ICV 1st.
Yeah going to same colour as the front mount pipes and air tank pipes
