I have run some tests on the fiesta.
I graphed the vehicle when the performance was poor. the results where, Accelerator pedal position in % whilst Accelerater pedal fully depressed would not go above 13% and the throttle position in voltage was giving readings in accordance to this. The accelerator pedal is new and genuine. what do we think is wrong and what should i do to get a fix.
When the vehicle is running good the APP will show 62%.
