O2 sensors
installed and seem to be working fine. Recommend a mechanic do this job unless you have a hoist and easy standup access. remind all purchasers that these are very fine threads holding the sensors in and after 150k miles of NE winters it is a time consuming and careful install. Now chasing down a vapor system light.
