its looking rather unlikely now that my car will be making an appearance at FITP

i have a big problem with the throttle body, it doesn't read the air flow and the idle is all wrong, then if i don't continuously accelerate it flashes EAC fail on my dash and cuts all power

also my surprise of fitting a cossie inlet just before the show didn't go well and we just couldn't get it to fit properly. the weird thing is that this problem i have now is nothing to do with the inlet change as it is back to standard again but by taking the throttle body off and cleaning it it has broken and doesnt have a clue what its meant to be doing.
i have got my car booked in at ford the earliest they can do is friday

so that looks like FITP is gonna be a big no no as if they need parts its gonna be monday before its fixed!
the list of parts i may need
throttle pedal sense £65
Throttle body £231
Air flow sensor £36
New part for ECU with fitting £700
i gotta now drive my car to ford which is gonna be fun as the only way to stop is take it outa gear and the only way to keep it running is to accelerate
