Hi techie people ive got a fiesta rst that ive been sorting out for a little while and mainly sorting niggly problems as i hate them more than big problems!!

Basicly i want to ask this question and confurm my suspisions or tell me im a cunt and say its this

Right my problem is its a standard engine and its starts and idles perfectly and wen its cold and u touch the throttle to rev it it bogs down abit before it revs up. It drives spot on and when its warm it doesnt do it atal.

I think it might be the valve stem seals letting some oil into the bores and not allowing the fuel to be burnt properly until its warms up and it does smoke a tiny bit on start up.

So what do u think???
