    Hello, jfrench830 and welcome to the Cadillac Owners Forms!

    P1415 is Secondary Air Injection System - Bank 1, which is the rear bank of the engine.

    Here's what you do, test the rear SAI shut off valve with a vacumm pump, the valve should hold vacumm and open when 10" of vacumm is applied. The diaphram in the valve is a common failure. Another thing that could be wrong is the vacumm line that goes to the shut-off valve could be loose, cracked, or plugged. The vacumm soruce to the valve comes from a solenoid under the engine cover, a lot of times the vacumm line gets knocked off during other engine repairs.

    Let us know what you find.

    Frank

    Thanks for responding, I am mechanically inclined, but I've never just inspected all up under my hood b4. Exactly where are these things you are speaking of.

    It is on the rear cam cover. Since you are mechanically inclined and do your own work a FSM will be worth its weight in gold. Ebay is your friend.
