EAC fail 1.4 tdci fiesta
I recently had a fuel leak on my 2005 Fiesta 1.4 diesel.
A garage replaced the fuel injector seals, high pressure pipes, air induction hose and leak off pipe which cured the problem.
A couple of weeks later the EAC fail light started to flash whenever I accelerate unless I accelerate very gently. It then gets to a certain speed (about 10mph in first, 20mph in second etc) and won't accelerate any more with a maximum of about 50mph in fifth.
I took it to a different garage as the first doesn't have the diagnostic equipment and about ten faults were logged but the mechanic said none of them relate to the EAC problem or the that the EAC problem related to the work that was done on the injectors.
The faults logged were:
p1934-driving speed signal
p2912-reverse light switch
p0102-air mass signal (x2)
p0113-air temperature signal
p0119-coolant temperature signal
He reckoned there was 'restricted engine breathing' so he separated the exhaust mounting flange but no change then he separated the catalytic converter from the turbo charge but no change then he replaced the fuel filter but still no change. He thinks the next thing to try is the fuel pump but thinks it's not worth paying for as it will cost a lot and might not solve the problem. He reckons I should just get a new car but I'm hoping there is an inexpensive cure.
Any help on how this EAC fault could be resolved would be greatly appreciated.
