Hi,
New to me, 2009 Fiesta 1.25L Edge 84bhp model.

Still under dealer's 3 month warranty.

When air con is on, the car has a flat spot, e.g. at about 2200 rpm I can feel it (in all gears I think).

If on flat or downhill, it will get past the flat spot and when get to 2900 the torque really kicks in as it should on these cars (still feels weird to me after my old escort and puma), otherwise I simply change down a gear.

With air con off the little engine behaves as it should.

Any ideas?

Thanks in advance.
