Also I know it's not to uncommon for there 2 B a grounding problem on 1 or both of the sensors.. Do they share a common ground? Thx all...

They are grounded to the firewall from the engine harness.

Do they share a common ground? On my PMS the left o2 is cycling properly stayin below 1 volt toggling rich-lean making corrections. My right 1 is from 2-3 volts.. Both sensors r brand new Bosch sensors. I will start with swapping the right & left plugs & see if it changes..

Yes.

Give me a minute and I'll dig up some diagrams.
