i drive a 2001 Type R and the only mod is an intake, and ive had the intake on for while, anyways I threw a CEL the other day and went and had the code read and the guy told me that i was running rich in bank one, i heard of cars running lean but not to many rich. what can i do to get this fixed... thanks.

 

what was the actual code numbers do you know (like po420)? You can go to autozone nd borrow their code reader for free and pulll your own code.

 

That usually is a faulty o2 sensor. Bank 1 - between the manifold & cat. Bank 2 - After the cat.

 

yea thats where i went, he didnt give me the actual code but thats what he told me, i hope thats all it is is an o2 sensor. ill look in to it to see if thats it or not, Anyother thoughts??? Thanks
