    My steps: All of them down to snug fit, then center, left outside, right outside, inner left nut, inner right nut and repeat until 21 ft lbf (As per the manual).

    Is there a factory recommended way or better order?

    I have a possible air leak somewhere and it is now throwing codes after clean install.
