You have to link the video from a video sharing site like YouTube. Air filter element look normal?

Air filter new K&N, just installed Werhli fab intake pipe and inter cooler pipes

An oiled K&N? If so, I'd suspect that. Actually the stock filter flows as good as any.

I’ll pull filter out see if it stops

Get some MAF cleaner and do that at the same time. That is very sensitive to being oiled and dirty.

I agree with BT Farm. Pull it and clean maf. I am a k&n user, have been for years and know how to get them to filter better than stock. But do not use them on modern engines with a maf. That is a recipe for problems.

Be 100% sure nothing got into the intake system when it was opened up. I once saw a guy missed the plastic cap that kept a new inter cooler clean-

You could have the turbo waste-gate freaking out doing this also- but I would expect engine code/ check engine light.

It wasn’t doing it this morning, but still put Wix filter in it and cleaned MAF, saw the cold side intercooler pipe wasn’t connected very good so fixed that also. It did set code fore barometric sensor after it did it but cleared and didn’t come back. Thanks for advice

Now if I can get the NOX sensor light cleared? Replaced NOX sensor #1 but still sets code after 5 miles

Late to the party. Was this during a regen? Did you ever find the cause? Thx.
