Hey, I wonder if I can get some very specific instruction to remove the CPS. I tried today for over an hour with no luck. Got light in there but for the life of me could not disengage the plug to expose the bolt. One suggestion was to attempt to unscrew the bolt first but the wire housing plug interferes with a straight shot for the socket. Which end of the retaining clip do you depress the clear the lock tab? Is it toward the engine or close to the end of the plug wire? I used a long round file for the end to use a push the clip cause my fingers (Strength) were not doing it. Any suggestions before I go to the expensive mechanic.
