Having a intermitant fault with my 2009 2.0 tdci focus. when the weather is damp and cold, if i am driving along at 70+ mph, the throttle seems to be unresponsive. There is no rsponse from the throttle if i try to pull away, so i have to stop on the hardsholder turn the car off and back on then it works again. This problem could happen once a week, not happen for weeks on end or even happen two or 3 times a day

I had this before and had to replace the fuel filter.

had a reply from jeebowhite for this topic which i have tried but seem to still be having the same trouble any body else have any ideas !!!!

If the fuel filter replacement didn't resolve the issue, did you get any warning lights or errors on the dash?

no warning lights or errors on the dash. just turn ignition off and straight back on and it works

That shows its a mechanical failure and I'm still suspicious of air disturbing the fuel mix and cutting the fuel, have you checked fuel lines and made sure there's no air in the fuel filter?
