Hi all

i have a fiesta 1.25 zetec

having issues with the engine under startup car starts up but the car seems to struggle for revs when cold and not have much power when moving off it also sounds diffrent from usual.

soon as the engine starts to get some heat into it the problem disappears and the car runs fine.

happens after the cars engine has gone cold for 2-3 mins


and ideas on what it is and how easy it is to fix

Cheers Chris
