Issue with my Focus

Evening fellas, before running it to Ford (or any garage) I wonder if anyone could shed any light on an issue i'm having with my 2010 Focus 1.6 Sport that's just literally hit 40k mile this weekend.

After the car has warmed up, when its sat idle at a set of lights or a junction, the car feels like it's skipping a beat and the car shudders/judders slightly, felt more through the pedals and steering wheel, however the rev counter doesnt budge and there doesnt seem to be a change in the revs. It does this randomly, somtimes every 10 seconds, sometimes every 20 seconds

I've borrowed an OBDII reader off a mate and plugged it in but it's not flagging up any error codes (yet). The car was serviced in April this year (not genuine Ford), due its MOT next month.

Any starters for ten?

Thanks in advance!

Finally got some spare time this weekend, so nipped down to ECP to grab some spark plugs, swapped them and touch wood, it seems to have sorted the issue, however looking at the plugs themselves they seem to be fine to me?

Either one was duff, or just taking off the HT leads and re-seating them or the coil pack might have sorted it.

Either way, it's sorted - for now! Yay

Cheers for the input fellas
