Fiesta Mk6 engine shudder 1.25 petrol 2004 manual
Well seeing that I made such an arse of the strut mount maybe I should ask about the engine one too...
So when pulling away, the car would shake almost like the wheels skipping violently up and down with a loud thunking (real word honestly) noise from
the suspension/bulkhead area. Had something similar with the volvo and guessed it was the lower engine mount which fair enough looked bad and worn out
with lots of play bingo, £12 sorted very easy fix...or not damn!
Oh well must be a suspension issue then and since the plan was to change all the suspension in one go (very cheaply done so why not?) any knackered
parts like shocks etc would be changed out and the issue go away.
Nope it hasn't! it's still there just the same  now this is getting annoying... I have to drive like a granny otherwise it bangs away
at anything other than snails acceleration levels. I haven't tried jacking the engine up to see if one of the top mounts is ripped but
can't think of anything else it could be, everything on the suspension (except the twanging springs) checked out a perfect and for the noise to
be completely unaffected makes me think it is something totally different.
Any idea's or suggestions? It's not an overly easily engine bay to see stuff in as it's quite crowded in there.
Thanks

open bonnet & strip off any plastic crap covering the engine that you easily can, if you can reproduce it with the handbrake on, great get someone
to do it whilst you watch to see whats moving. If you can't reproduce with handbrake on then get someone to do it at pull away whilst you trot
alongside, you should be able to see what's happening. Sounds like excessive play in engine mounts, have you tried rocking the engine by hand,
or with a lever?
I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator
headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names
furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.

Lower engine mount sounds a likely candidate to me. The rubber in a 205 GTI lower engine mount is known to perish/split after a while an allows the
engine to try and rotate. This can then cause shudder when you try an pull away as the lower engine mount is right where the drive shafts exit the
transmission.
russbost's suggestions seem a pretty valid way of checking.
After that getting uner the engine and levering it about around the lower engine mount might show you.

took the top mountings off but before I did I noticed the drivers side one had been removed before as it had a new water pump and that it was
positioned further backwards from the original paint marks round the bolt when it left the factory, quite a bit actually as the bolt holes in the
mounts are very large and it can slide around until bolted down. So I check the mount which all seem in very good if not perfect condition but pulled
the engine right forward as far as I could before tightening down and the seems to have cured the banging. So was just badly re-positioned engine
mounts...perhaps the cat was thumping into the bulkhead as that's a fat thing on the base of the manifold.

Weigh it in and never buy another Ford? That's what i did last time I had a Fiesta. It's a policy that has served me well ever since

tbh I'm very happy, no delighted by the car so far 
Just a year ago I completely fell out with Fords with the C-max falling apart and then the dual mass clutch going, couldn't get rid of that car
quick enough...
But the wee fiesta, I don't know just really seems to be spot on. It's rough round the edges like any budget car (mines the basement model
1.25 petrol, I don't even have electric windows) but its design so far has really impressed me. It's use of space is fabulous, had 3 bikes
in it, carried 7 full size radiators yesterday along with a weeks shopping, ok there was no suspension travel left but it didn't blow up...
Once I've paid off the wife's car in a couple of years I'm seriously thinking of treating myself to a brand new one  which I
will look after with totally insane devotion
