Hey there. Does anyone have anything for me? I swapped my SOHC in my 2000 GT auto, to a 2001 DOHC Cobra 5 speed, now it smokes after car is warmed up. It smells like it is burning really rich. I had a shop set up my Excalibrator 2 to turn off back O2 sensors, but it still does it. After I rev up the engine it takes a few seconds for it to idle be to normal. It idles back to about 1100 RPM before returning to normal after a few seconds. Is it maybe the front O2 sensors, or is there something else causing this? I would really appreciate some help with this. Thanks
