Being in the field for 16 years I can say this is a 1st for me!

Looks pretty ok to me. Probably what a lot of parts on my yukon look like

Funny thing is, it never set a MAF code. How in the fuck?! I was getting Fuel Rail PSI codes.

Maybe the maf was reading wrong causing the psi issues?

DAT DIRTY!

The MAF reading wrong caused PSI issues.

It was commanding 128 mpa rail PSI at idle when it should have only been 30 mpa.

I just cleaned it, gonna let it dry and see how she looks. Have a feeling a new MAF in needed.

Holly shit! That's why I clean my maf at least twice a year.
