My o2 sensors are off the chart. try to start it and loud backfire
Any ideas?

Have you crossed left and right front O2 sensors...? If you do that, car will run in SD mode until temp is up and closed lopp is entered, then Everything fails..

[blown00ta]

Do you mean the o2 sensors them self? Dont think i can cross the harness connectors.
Mods are:
05 ls2 long block
cam
headers
fast 92/92
zo6 maf
42# injectors.

Post the tune. By looking at the O2 sensors voltage, you are dumping tons of fuel.

[blown00ta]

here you go.

What injectors are you running on this setup?

[blown00ta]

Ford green top.

Also i'm not running knock sensors.

Check your O2 Rich/Lean vs. Airflow settings. They have been changed to something different than stock. Once you check and change, do another log and see if that corrects the problem.

ok got brand new 42# injectors now o2 passenger side reading rich driver side lean.
fuel pressure at 58psi.
maybe intake leak?
no headers leak.
when starting the car sometimes it cranks poping in exhaust.
any ideas would help alot.

with it lean one side and rich on the other i would really lean towards crossed 02's you really need to double check!!!!!!!!!!!

[blown00ta]

What do you mean crossed o2? sorry i'm little lost.

[blown00ta]

I also noticed that my low oil light is on but its not low.
i'm thinking I might have a burnt wires on passenger side which is why its running rich on that side.
funny thing is I have no codes poping up.

[mbray01]

you really need to trace out all wires and check integrity of the circuits, and "FIX" and bad wiring. You cannot expect the thing to run right if it is not receiving all the proper signals. I know your looking for quick answers, but I think your just gonna have to bear down and start fixing wiring. Now as for crossed o 2's trace the wiring from o2 to ecm, with a wiring diagram, because I would bet that the left 02 is in the right o2 spot and vise versa in respect to the wiring. As much as you think it's not possible it happens all the time

update.
took ecu off found blue connector has water damage. swapped out computers an now both side read lean but idle is better.
here is a log.
