Anyone else notice that the car runs a little erratically when the A/C is on.I guess it,s when the compressor cuts in ,but you would of thought that with a 2.0 litre engine this shouldn,t be a problem.
I think that when we start to go for our first services several subtle touches to the ECU will be made by Ford.

i noticed it also, it holds back a little at that moment. but i think that is because of the light flywheel in the and the lower torque in the lower revs. i didnt noticed it that much in my old MK6

The problem is really when you,re pottering around town.Don,t notice so much on the open road.

Aircon takes alot more fuel and you may notice it...

It really bogs my 1.8 focus down when i have it on... when i stop i turn it off until im moving again or i feel asif i dont have any power.

Nothing to worry about but remember it will cost about £7 a full take of fuel if you keep it on!!!

I always seem to feel guilty when I put the air con on. Maybe cos of the extra juice it might burn. I'd rather just open the windows, although I appreciate that this creates more drag which increases the fuel consumption. Can't win.

yeah but at 0.98 Euros a litre I,m not complaining.In the summer when it,s 40 degrees you can bet I,ll have it on all day for 6months.Don,t have the spluttering problems either maybe the higher temperatures down here.

My last tank full of fuel I averaged just over 30mpg and that was with the air con on the whole time and most of it on the motorway at 80-90mph.
