Hi all,

My Ford Focus ST 225 2006 has a very annoying issue;
When I select 6th gear and am doing say 30mph, if I put my foot flat to the floor, (Still in 6th) I get an ESP System Fault, and loose the majority of the cars power as the turbo switches off. I have replaced the Fuel Rail Pressure Sensor but am still having the exact same issue. Does anyone have any suggestions? Or know what the actual issue is, I'd appreciate all suggestions and help.

Thanks for your time.

Jordan
