I have been having problems with what is a common fault on my 2004 1.6 Fusion Auto where it goes into engine fail, fault codes always show either throttle pedal or throttle body. I have changed the pedal and throttle body and over the last year I have been working on the ECU plug. Its so intermittant that it can clear by moving any part. Then next time, takes days to settle down. It could be the ECU but if it is sent off for testing it will no doubt come back as fine. My garage has been advising and they have seen similar before so its just a game of chasing and checking everything. So just before I bite the bullet to replace the ECU I want to check all connectors between the ECU and throttle components. Are there any in line connectors and where are they? Does anyone have a wiring digram that has this level of detail so that I can inspect all connections.
