Hi there hope i can be of assiatnce.


Ok this means there is a fault with the acceleration control. EAC means Electronic Acceleration Control.


The usual susopect on the 1.25 duratech engine is the throttle poteniometer. This is intergrated into the accelerator pedal.


It will restrict your revs to 2000rpm as the car will be in 'limp home' mode. This prevents any further damage to engine components.


The fault will be able to be easily and quickly diagnosed with the aid of a diagnostic scan of the cars on board computer.


Thanks bob
