Found this page with the fault code I have got p0641 could the pedal or throttle body have an interference and cause this problem to trip the management light and have the same symptoms? http://www.bba-reman.com/content.aspx?content=ford_fiesta_common_problems_and_solutions

Hi my local garage said I need a new ecu but since getting my car back after the ecu was tested and passed the test, it seems to run a little bit better. Do you think that this could be what I need (new ecu) They said to get a used one and to get it coded would be 300 plus. Any ideas?
