Hi all, specially to Deville33 and BruceRoe.
Well, today i received the service manual for the 1977-78 cadillacs, first let me tell you the material is great, i only take a quick look overall is very nice.
I took most of my time trying to find out wich one is exactly my car, and then i found out my car is a California car, why? because looking into the EFI VACUUM DIAGRAMS i was able to figure it out.
Well, this is the California diagram:
Now lets get to know what is wrong and why and what happens?? this one you will have to help out.
this is the first problem i found:
The AIR PUMP DIVERTER VALVE, what is the function of this part?
The distributor TVS is supposed to have 3 outlets, mine only have 2, thats why one of the vacuum lines from the "T" have a screw on it?!?
I will continue with the other problems.
