    I changed my spark plugs a couple days ago, and my truck ran fine for a day. Today, my truck went into limp mode and showed codes p2441 (secondary air injection system switching valve stuck closed bank1) and p2445 (secondary air injection system pump stuck off bank1). I see a couple other people have experienced similar after changing plugs, and I'm wondering if anyone has a solution. Thank you.

    Edit: Upon checking all of the lines around the intake resonator a third time, I discovered I had pinched a hose to the air switching valve (?) under the intake resonator mounting bracket in the back and out of sight. Everything seems to be running ok for now, following my clearing of the codes. :facepalm:I'll leave this up for other drunk mechanics.

    The resonator is the the black "box" setting on top of the engine. The one the intake tube goes into.....
    The bracket is....well, it's self explanator. Pop your hood and look for the bracket that the resonator bolts to....
