I've been getting these codes for awhile now which are p0174 "ECM has detected a rich or lean air/fuel ratio on bank two" and p0171 "the power train control module uses the oxygen sensor to calculate the air/fuel ratio. The computer has recognized a rich or lean condition on one engine bank only" which confuses me because the other code says it's on bank two as well?
Now, Originally I thought it was my custom cold air intake I installed but I'm starting to believe it's not. Some symptoms is my cars idle seems to be rough intermittently especially when it's cold out and my gas mileage has went down.
I Thought it was a vacuum leak but I had it smoked checked and they said nothings showing. I even went with uninstalling in entirely and reinstalling to make sure there was no leaks.
Reset the ecu by unhooking the battery over night and I'm still getting the code.
It's saying the exact definition of this code is p0171 "fuel trim bank one condition" and p0174 "fuel trim bank two condition"
It says if these codes pull up together expect an MAF sensor fault (which I don't think it is, I even cleaned it with some CRC) 02 sensor but I don't know which sensor it would be. Bank 1 and 2?
Also it says it could be a fuel injector or misfire
I don't know where to start guys. Please Any help would be appreciated.
