Just the throttle body, I shall be doing the connectors this week. Also hopefully get my fault reader tomorrow or Tuesday so can see what code that throws out. Is there a list of the codes somewhere?

Well I just caught an EAC Fail and had my fault code reader in at the time it happened, however the reader said No Faults.... Broken reader or a silly Fiesta error? Dave?

It's the connector's they need cleaning. Especially the throttle pedal connector, I know Fiesta/Fusion had an issue with this until 2006.5my when they changed the plug pins and pedal to gold connectors as the Air Con can cause condensation in the connectors.

For a split second you get a miss-connection which throws the lights up then it re-connects and shuts them off again.

Certain faults are given priority (safety critical parts etc etc).

Some components need to be faulty once to put the lamp up
Some need five driving cycles (key out-key in)
Some need twelve.
Some put codes up as a notification that there WAS an issue, whereas some are live.

You need to disconnect the battery earth (-) terminal and disconnect and clean/spray the following connectors AND ports:

Throttle body
Throttle Pedal
Alternator

then re-connect the battery.

Failing that then the motor is on the way out on the throttle body.

Thanks for the help Dave. I shall spray all the connectors this weekend as I have a day dedicated to getting my car looking good again.

I suspect it might be a new TB as after I cleaned it, I didn't get the EAC fail for a couple of weeks. I shall see how I get on though and let you know.

Cheers

That'll do it.

As long as it says it's suitable for electronics.

You may want to silicon grease the throttle pedal and body connectors as well after you have lubricated. To keep future moisture out.

Remember to do it with the battery disconnected and to connect/disconnect the connectors a few times to really clean/settle the contacts.

You haven't had the engine bay jet washed at all have you?

Ok, I'll do that.

Nope, I've never jet washed the engine. Why do you ask?
Don't think the previous owner did either, don't think the previous owner actually looked after the car properly
