I have a mk3 1.8 petrol Mondeo which is in excellent condition. My problem is that there's a really noticeable "flat spot" below around 2500 rpm. It's like the throttle cable's made of elastic.
It starts and runs really well apart from this, so I'm a little mystified! It's had a new coil, plugs and leads and I've cleaned the throttle body and MAP sensor.
There aren't any fault codes either, so I don't know where to look next. Any help would be great!
