Ok, this is for the EEC gurus..my buddy has an 89 gt like mine with almost identical setup..all of a sudden he started getting a check engine light...with a code 66 - mass air voltage below minimum value. When the light comes on the car starts running super rich and smoking out of both pipes. He has tried a new mass air,new processor, and replaced the harness between the processor and the mass air. The car has a new eger,evp, o2 sensors,iat and idle air motor...any suggestions? Only thing that has not been replaced is the baro..but it checks ok.
