I have had a BBK OR X pipe on for about a week and the CEL turned on yesterday, I went to Autozone and they pulled the codes:
P0420 Catalyst Efficiency Below Threshold in Bank 1
and
Pending P0174 System too lean Bank 2
And I now have a leak on the drivers side, it isnt huge but can be heard at idle as well.
Couple Questions:
Which of these is because of no cats or are they from the leak on the manifold to the midpipe?
Could an exhaust leak cause the car to almost stall at idle and then catch itself and go back to normal, or is it the IAC? (It only does it when Im stopping at lights, not when I first start it at all.)
Thanks for any help :SNSign:
