1999 'HOE' CEL code

[chitown906]

So this has been an on going issue with our Tahoe and I would really like to figure it out so I'm hoping someone here may be able to shine some light on the issue. Purchased a Spectra Intake, and installed it now for whatever reason we're getting a 'Check Engine' light come on and it brings up the code (p0172/P0175). We've changed the MAF 5times now and the longest they've lasted was roughly a month.

I've checked all the piping coming from the intake into the filter and this issue was not present with the stock airbox on so that is where im really confused as to why the MAF wouldn't just adjust, and if so what other avenues to I have.

:flame:

Any and all help is GREATLY appreciated.

Thanks

did you put the old intake back on? Look at the maf plug, anything bad?

System too rich/bank1, system too rich bank2, do you have a FPR leak or something?
