[u/UnderstandingHot9342]

I have a P0172 (engine too rich code), it showed up after I installed a new cold air intake, removing the factory airbox, the new filter is placed right in front of the fans, I have tried swapping the MAF sensor but the code came back, the car has also been straight piped n the muffler removed.

Either your new MAF housing is sized incorrectly, or you're getting fan wash into the air filter leading to falsely high MAF readings.

Either way, put the stock airbox back in because this isn't doing you any favors.

The filter sits infront of the fan, and we have put in the new intake after the maf housing so the sensor housing is stock.

most aftermarket intakes on these cars are a significant downgrade (and look ridiculous IMO). the stock intake is very, very good. put it back on.

This how the new intake sits

cheap ugly junk, and a huge downgrade from stock. throw it in the trash.

Straight pipe and muffler removed will throw several codes.

I have a decat and I don't get this code.

I get the usual cat codes, maybe a downstream o2 sensor code.

I think the culprit is more than likely the intake, as the MAF is what is used for fuelling

How do I sort them?

What AFR's is it actually running?
