P2195 , P2197 codes
2008 F-150 4.6L
Lately I've been getting intermittent 2195 and 2197 codes. Sometimes they will disappear on their own and the check engine light will disappear. A mechanic replaced both Bank 1 and Bank O2 sensors. Same intermittent problem continues.
Tomorrow he is going to replace the spark plugs and figures that will clear the problem up. This weekend is the last one before my warranty runs out.
Is there anything more I could or should do to ensure the problem has been found and sorted out ? Is there another sensor that could be triggering these codes ?
