Ford Fiesta Juddering At 2000Rpm

[Colddust1984]

Hello all!...

Well I have a little bit of a problem with my beloved Ford Fiesta 1.4 Zetec 04. I will start from the beginning i was driving out of London on the M11 and I got a EAC fail on the dash and my car went into limp mode so i pulled over and called out the AA...After 30 minutes of the AA guy poking around he eventually discovered that the coil had gone and replaced and everything was grand, car was back to normal and drove like a dream.. However, I noticed the car struggling a few days later through 2nd and 3rd gear I thought i was in the wrong gear so I ignored it until the engine warning light flashed... I thought oh dear, so I changed the spark plugs and the car was back to normal for about a day until it started struggling once again but the juddering is so much smoother...now. I have really adjusted my driving style to stop the Juddering... I am going to see if new HT Leads make and difference tmr...

I've read on other Ford Forums that this fault seems like a "red herring" and is very difficult to pin down. So would anyone have any clues to what the fault could be if new HT leads don't do the trick....

P\S Its not water on the plugs been there fixed that rubbers on Jet washers..... :)

Any help would be great :) :) :)
