Very interesting Ray, thanks for the input.
I've already had to replace the rear O2 sensor so why not the front too, .....

Would you buy another OEM Front O2 sensor or something else?

I'm going to cross my fingers and hope this magically goes away.

 

I never had this "problem"

but I replaced my Front O2 like 15K miles ago so I guess thats why ? (I got that sensor from you Ray Remember? )
