PO171 CEL Code Need Help
 

Alright, I've had this code for a few months now and I can not find the problem. I have a problem with low idle and loss of power. I am all out of ideas and I need help to fix this. When I pull the CEL code it comes up as a bank 1 02 sensor so I replaced the pre-cat 02 sensor. Well that didn't get rid of the code so I replaced the MAF sensor, and that didn't work. I have replaced vacuum hoses and checked for leaks and everything is sealed tight. I am out of ideas and running out of money. Does anyone have any ideas to get rid of this code besides breaking the bulb for the CEL? :silly: Any help would be greatly appreciated I need to get this fixed.
