I need to replace my sensors and i have the bosch 13111. Just wondering if i should go back with them or go with stock?? Noticing alot of black smoke when i do the first WOT, after that it wont do it again til it sits for a while or drive normaly for a while

 

From what I have read it is recommended to go back with OEM sensors

 

Ok well im buying some new O2's in a week or so and i do have the 13111's in the truck, but i do know that i swapped pins in the connector and i dont remember what was swapped....

Could anyone help me out on trying to remember the thread on here that told what wires to swap??

 

I went with Delphi ES20022, just under $80 shipped from Amazon. These and AC Delco are what people on here recommended. They did not need any wire swapping. They are direct fit.
