Had my Focus for little over 6 months now, and up to christmas it has been faultless.
However, just before the christmas break, it has started intermittantly stuttering whilst driving. It doesn't happen at low speeds, or once at high speed, but seems to be if you 'give it the beans' and accelerate quickly.... but again.. not all the time.
The ting that seemed to start it off, I let it run quite low of fuel (roughly 20 mile range left), then I parked it on a nose up incline.
Then, I refuelled and it was after this that it began stuttering when accelerating.
I did think maybe I'd pulled some cr*p up off the bottom of the tank by letting it get low, and the incline of the hill. I have since refuelled a couple of times and it still happens... again, not all the time, but enough to begin concerning me.
First option was to change the fuel filter, and hope it is just dirt/debris in the fuel line.
But could this point to anything else?
Other than this issue, the car runs fine - though a little thirstier since the cold weather started.
Cheers for any replies/advice offered.
