Pete kim Posted January 28, 2009 Share Posted January 28, 2009 I have tried searching for hours, results turned up nothing. I have been trying to figure out if a vaccum leak will cause a code po171. where are the most likely places that these cars leak vaccum. its not the o2 sensors because I just replace them, and MAF has been cleaned. Car was showing 3 codes for o2 heater bank 1, bank 2 and PO171. The ecu is trying to compensate for the lean condition because its running pig rich. lost 5 miles to a gallon and the lean condition code is still present after i cleared it. any help would be appreciated, thanks guys Quote Link to comment Share on other sites More sharing options...
