Eac Failure

[MountG]

Hi Guys, first id like to say hello as im new to the forums.

This topic has probably been touched on before, i have a 2002 fiesta 1.4 zetec that is owned from brand new with no mods made to it. I've been experiencing a regular occurance of the dreaded EAC failure light putting the car into the 10mph limp mode. I've taken the car to ford who did the diagnostic check and said i need a new PCM after they reset the PC providing that didn't solve the issue. I then took the car to a smaller garage where i had the diagnostic check done again, they said it could be a series of problems ranging from an accelerator replacement to a new ECU and wiring harness with no reassurance that would fix the issue. Has anybody been down this road with their fiesta? Ive searched and searched the internet for possible solutions and im bit reluctant to part with more money than the car is worth so a starting to point of any sort of fix would be very much appreciated. I have supplied the codes of the diagnostic report below. Thanks for in advance for anyone that may help.

P1238 , P2135 , P2176 , 2119 The faults mainly cover throttle and sensors aon the report but was advised it could be a number of reasons.

Cheers guys...
