"Â P0412 Secondary Air Injection (AIR) Solenoid Relay Control Circuit Bank 1

When you run an engine, basically there is unburned fuel that is forced into the exhaust. To avoid excessive emissions, and premature catylatic converter failure, air is forced into the exhaust to allow the continued burning of unburned fuel. What is happening is you have a bad relay for bank one that is preventing this from happening.

If you hare loosing that much power, chances are the catylatic converter is failing and causing too much back pressure. Check the converter to see if it is plugging. Also, have the soleniod relay checked to make sure it isn't stuck in an open circuit.
