Hi, I have a 2005 Fiesta ST Mk6 facelift.
It's currently starting up and going to 2k revs, then settling slightly then erratically skipping between and bouncing slightly.
I've swapped the throttle body out for another used, but tested one from a guy in an ST owners club.
Its still behaving the same and I still have no dash lights or errors at all otherwise.
With a live data scan it shows the throttle sensor jumping up and down causing the revs to bounce.
This sensor is in the throttle body unit and works on other STs, so, what could be causing this?
I can't just change the sensor and a new pedal unit from Ford is 400 bricks.
Please help, ive been scratching my head for weeks! D:
