Hello and Welcome to justanswer..My name is XXXXX XXXXX Im happy to help you with this - Can I just ask - have you got any / get any fault lights come on at all when this happens - or when driving?Too - have you had any plug in tests done at all - standing and in driving?Plus - the plugs and leads you fitted - are you sure they are the correct type / Ford issue etc?
Also- when was the last oil change done - mileage / time wise.. ?Rgds - MIKE...............................
No fault lights have come on.
I guess when you say plug in tests you mean connected to a computer. If so, no, I have not done this. I want to avoid the cost.
As far as I am aware they are the correct plugs and leads. Got them from Euro Car Parts.
The car last had an oil change about 12 months ago which was at about 90,000 miles.
Thanks I will try that. Do you know why the fault would only happen in warmer weather? I would have thought if it was valves or injectors it would happen regardless of outside air temperature. Below about 10 degrees C the fault doesn't seem to happen.

Thanks, XXXXX XXXXX won't get a chance to do it until next weekend but I will let you know how I get on.
Sorry for the delayed response I have not had computer access for a couple of days.
I won't know how to rate your answer until I have done what you suggested.
I have bought the oil, oil filter, and engine flush and am borrowing a pair of ramps off a friend tomorrow. Weather permitting I will get the job completed tomorrow evening.
I carried out the engine flush and have finished one tank with injector cleaner but this has made no difference. Any other suggestions?
I read somewhere it could be a small split in a vacuum line and when the ambient air temp is warmer the split opens up and when it its colder it is closed. Does this make any sense? Or do you have any other suggestions?
Something else which I have noticed but may be unrelated, when I am slowing down and put it in neutral just before I stop the revs will go up to about 2000 rpm and then when I get to a complete stop they drop down to normal idle speed. If I am stopped on a hill and then start rolling forward the revs will go up again until I come to a complete stop again.
