I finally reconnected my factory harness to the front O2 sensors hoping that would stop my ECM from puking. Installed the Brooksspeed tune and wouldnt you know it, ck engine light came on after second ignition startup and got my old friend 0059 showing up again. Im beginning to think Brenspeed was correct about JBA headers and the relocation of the front O2 sensors being a tuning nightmare. Any further suggestions or comments constructive in nature would be welcomed.
What was Brenspeed correct on JBA Long Tube headers??? I have them on my car also and I have had NO problems. I had the car dyno tuned and I have NEVER had a problem since the install was done.
Have a you called some tuners that have tuned a bunch of LT cars and asked questions?
