Awhile back, I was gettting an Error Code stating that Bank 1 is stuck on perminately closed.
Error Code .P2441
I figured it out!
Took the car back to the dealership, and have them look everything over. Turns out that the Switching Air Pump Gasket was installed incorrectly by my mechanic. They also removed the headers, and re-installed them to make sure it was okay.
Also, I switched fuel to 91 octane from 89, and no more check engine light.
Here's my setup.
Aero 2525 Muffler.
AFR Cold Air Intake.
Doug Thorley Exhaust headers.
