Anyone came across this code?
"P0172 system too rich bank 1"
Probably dirty intake filter?

 

Did you recently get a new intake?

I had that problem once and it was because when I installed the intake I didnt make sure the MAF sensor was 100% snug fit into the housing.

 

i had that issue when i put in an aftermarket intake. burnt the O2 sensor so had to get it replaced =(

 

wow, BURNT the o2 sensor? what intake was that??

 

i had that when i installed my intake....a tube slipped off so i got some clamps from autozone

 

had the intake since April, the the code just came up yesterday

 

did you do an oil change recently? i had that code threw on me right after i had an oil change

 

Change out the spark plugs or coils recently?

 

Yup, a few days before with Mobile1 ext performance..


Already did spark plugs about 5K miles ago

 

^ that!

Not sure why, but i had the same issue after an oil change with that oil. I even got horrible cam gear noise everytime i start the car.

I drained it after 1k miles and fill it back with regular Mobil 1 and the car ran fine..
