There isn't much written about changing Oxygen Sensors in any sort of schedule --- maybe when they cease talking or won't heat up --- and they'll pop a code anyway........

... but I DO know that an engine will perk up with new ones.

Just to let you guys know, it looks like problem solved. I checked the fuse and replaced it... again. but since, no codes.
Keep my fingers crossed. Thanks Guys.
