I've got a '98 1.6 Zetec-E lump in my escort and its got an annoying mis fire from about 750rpm to 1500rpm ish which is worse when its cold. in the last 2 months, i've replaced the spark plugs (BOSCH ones), fitted a new ICV, a new throttle sensor and a new MAF sensor. it had a new fuel pump fitted in october and a new fuel filter fitted in the summer. i've got no more ideas now on what i could be

the cars done 67k and has been serviced every 6k by Ford. the misfire was worse b4 i replaced the MAF but its still there

please help!
