Just a quick note regarding o2 sensors - the NGK brand o2 sensor, which is actually an NTK o2 sensor is the same item as the genuine ford item.
If you look at the ford item, it has NTK stamped on it.
They are available from repco etc...
If it is running rich, and youve already replace the ECT sensor, try disconnecting the vacuum hose from the MAP sensor, on the firewall and see how it runs, if it is worse, then the map sensor may be ok, however if it makes no difference, make sure the hose is still connected to the manifold (ie has vacuum present) or replace the map sensor.
The other reason it may run rich, is if you have an o2 sensor fault, reading constantly lean, therefore the ecu compensates and richens the mixture.
As stated ECU's generally dont cause any dramas, but from time to time you will see a falc with a leaking windscreen or a leak around where the wipers are, and the water usually drips onto the ECU,
It wouldnt hurt to take the ECU out and check for moisture. Remove the connector from the ECU (10mm bolt) and also check in there.
From wreckers you shouldnt pay any more than around $130 for an ECU, EA ones being cheaper, but if its MPEFI and has smartlock, you can replace it with an EBII or ED unit without any hassles, as long as its an AUTO Ecu,
FYI An EBII auto ecu may have the code 1DCE on it (thats one of the many, but it may help in finding one)
