try cleaning and soldering the ground connections on the intake manifold. Put "star"washers on the bolts for the grounds. There was a problem with lh 2.4 cars throwing an ect sensor code 123, becuase of faulty grounds on the manifold, instaed of a bad sensor. When I've encountered this code, i do both the sensor and the grounds, sometimes the thermostat on motronic cars will cause the efi 123 code. Clean the grounds and solder the wires inside the connectors and let me know if it fixes it. If not, I'll do some looking around for tech notes.
