For a while my 1.8 zetec (105ps) has had a prob. Every now and then when i go to pull away itll misfire or when say sittin on motorway holdin the revs itll do the same and lose power. its confusing me as when u full throttle it clears and runs fine till u go back to part throttle. i serviced it which cleared it for a week but now its back. it blew a rad hose the other day so got a new one, new coolant etc and cleaned out the idle control valve whilst i was at it. not its terrible and will only really pull away at near full throttle otherwise it misfires. any help gratefully received guys, and girls, of course
