Ford Mondeo acceleration juddering
Discussion
Morning, New member here.
Ok a few months ago the cr went into "safe mode" with the glow plug light on, My mate said change the cam shaft sensor, I did that and it wasnt resolved, The car was smoking etc, I took it to a mechanic mate that changed two injectors.
The car came back like new, Although i have a bit of rattling which is apparantly the alternator tensioner (which i will get done) i have a new problem.
The car is juddering and missing slightly up to 30mph and is quite noisy at times, Although there is no definate pattern to this, Over 30mph its fine, No warning lights on at all.
Today though ive driven up M5 about 80 mile round trip and experienced no problems at all!
Weird!
So based on the fact i know nothing about cars could it be
A- fuel filter blocked?
B- The remaining injectors failing (presumably a warning light will appear?)
C- Something else
Many thanks for any replys

Checked the egr valve?

I did the above to my '07 +100K miles Mondeo and it made a hell of a difference (also combined with a decat and egr blanking plate, also recommended). For the princely sum of about £80 I was saving nigh on £50 a month in fuel AND it ran smoother and faster.

EGR valves can be a pain. On my previous car (not a Ford) it was a regular problem. Cutting out, juddering and failing to start, or any combination of all three! But my current Focus doesn't have an EGR valve, it has variable valve timing instead. This apparently does the job of EGRing.
My mondeo ST TDCI has just gone into the garage for 2 injectors going belly up. Had juddering acceleration then on tuesday. I struggled to get it to move in first, kangarooing very badly, loads of black smoke and still had 120 miles to go. Thank god for the RAC and UK wide recovery. RAC guy suggested injectors as soon as he heard it, and got the call from the garage yesterday informing me that both 2 and 4 injectors were duff!!! 
Hope yours gets resolved easily mate.
