Got an odd one with my 2001 1.6 Zetec Focus.
Trying to accelerate with anything other than light throttle input (less than 1/4 pedal travel) means the car stutters and loses power, if you back the throttle off a bit it picks up and runs as normal.
The engine management light flickered a few times and is now on all the time.
My thoughts are that its either throttle position sensor, as the fault seems to happen at roughly the same throttle position, or possibly MAF or plugs / leads or even coil pack.
The coil pack is only about a year old, but im not ruling it out.
Anyone else had this or got any useful suggestions?
Thanks
