Hey all. Reread this thread again, but I'm a Noob when it comes to electrical.

What I'm searching for is a clear, "talking to a 6 year old" type description of how to confirm the problem is NOT electrical, prior to replacing the secondary air check valve. And if possible, confirmation the valve can be reached via the pass wheel well, with car on lift.

This thread is a godsend -- the threads on M5Forum all go down the winding road of carbon buildup, not helpful.

Thanks in advance.
