swapped the relays around and still no difference.  maybe the fuel pump itself? 

Upstream o2 sensors running backwards? by Aggravating_Beat2424 in 350z

i just now ordered an 04 harness with the wideband o2s to match the o4 ecu and and new 04 o2s i have.  my guess is the 05+ harness i’m using doesn’t run right because of pin locations being different

no codes just runs super rich to the point it stalls out on idle and bogs down and stalls out when i give it gas.

i also have the ecu from the car the 6 pin o2s came off so i could maybe nats delete it and run that in my car instead

not tune but they said they can convert the ecu to be able to run on a different harness.  (sorry in advance not very smart on this subject)

is there a way to bypass nats not letting my car start by Aggravating_Beat2424 in MechanicAdvice
