Do i have to move the seat to get to the 2nd bank wiring of the o2 sensor ,its a 4cly. anyone have info on this did a search but nothing on it. any pics

 

No, pull back carpet from the floor rail under the front edge of pax seat to expose the secondary wire penetration through floor and connector. Disconnect, push penetration and wire through hole, remove cover, remove secondary O2 sensor (special tool or large open/closed end wrench). Warming engine for 5 minutes may help w/ removal.

good luck
