I have 2 consistant faults happening P1137 and P1139 which are O2 sensors. The car runs great and has 185K miles on the engine. Anybody have any suggestions before I look to having the pricey O2 sensors fixed??
I will do that first. No there are 4 O2 senors 2 in front and 2 in back and they all are approximately $135 each that is doing the job yourself. Any dealer want at least $200 per sensor before labor. Thanks again for suggestions I will post what I find out for anybody in the future.
