Hi, i have a fiesta 1.4 tdci on a 04 plate, always been reliable motor however..... a few months ago ea fail come up on the dashboard and went into limp mode (?) restricting revs to 2000, pulled over switched off etc restarted car and all ok for a while! this continued but with the frequency increasing until i have now got it on permanantly. Got a mechanic to have a look, this resulted in diagnostic check showing the following P1204 Cylinder 4 injector circuit open/shorted P0204 Cylinder 4 injector circuit malfunction The number 4 injector was renewed. The injector top wiring loom was renewed. The accelerater pedal was renewed. Retested and reset but alas the problem persists! Can anyone give me some help or guidance?
