lumpy acceleration

Hi everyone
Been a while since I was here posting problems (less then 6 months! lol) but been observing regularly. Have a scenario I would like advise on.
I have 1.4l freedom 2003 - petrol model. in the last month, under acceleration (especially noticeable in first 3 gears), the car seems sluggish - put foot down and she jerks a bit until she gets over a certain speed/rev count. Best description - like when trying to move off/accelerate in too high a gear.
now thing is - car got her ignition coils done about 18 months ago (they went taking out ECU), and got her exhaust, alternator, new bat and Catalytic convertor done back in July. Spark plugs also done around 6-9 months ago.
Been toldit sound like classic HT lead and Ignition coil renewal. Now I have noticed one of the HT leads does lift a bit so needs a push down at least daily now (more to be safe) - so that is on the cards. Are these classic symptoms of a dying ignition coil/lead set? Is there anything else I should get her checked for? (cheap enough to do leads and ignition coil - and seems simple enough too)
Really appreciate your time reading this - just need to look at my options and how to go forward. (please excuse spelling mistakes - wrecked from work)
Thanks :)

Remove the coil and check it for any cracks. If it is, replace it with a new Motorcraft coil. Any other manufacturer is crap when it comes to our coils.

Also check the coil pigtail connector for any cracked or exposed wires. If so, buy a new one and solder it on.

The cracks will not be staggering, rather fine ones that are easier to see in strong light. Look at bottom of coil too.

open the hood at night in the darkest dark, engine running

then mist it with any spray bottle....if she lights up like a christmas tree , start eliminating the largest sparks first.

Hi all, this has now progressed - engine management light has come on (200 miles into trip). Can coils activate this?

Anything that causes a misfire can cause a CEL, computer looks at crank sensor data to see if it's running smoothly. Bad enough & you get a CEL.

It can also light for a specific problem leading to the trouble, like a wiring/coil fault.

Hi all,
Sorry - am a bit under the weather at momen, hence delay in reply.
Tried booking Car in four diagnostics but between my own mechanic being busy& no way of getting Car to /from ford, i didn't get her plugged in.
So bf&I replaced ignition coil & ht leads, checking spark plugs too. Coil looks perfect, no visible cracks of any sort. Ht leads - for plug 2 wasn't clicking down right onto plug, 3&4 were bit corroded.
Since changing coils&leads, the car runs good again, CEL went off too. So that looks good - done over 100 miles since. Should i still get a diagnostics done?
Plugs 3&4 - they had a bit of oil on threads, tips were a bit tan in colour - what's that mean? Can't remember what it means :-(
Thanks.
