ECM reading 1350 F. on Cats
Is the ECM responding to this by changing any factors on how the engine performs? Im running LT headers no cats (rear o2's tuned out) MagnaFlow catback. I found it very strange how my scan tool was reading such a high temp? Does the explain why i have such a rough idle and stumple between 1200-1350rpm?
Thanks in advance!

Car will respond with cat's over temp mode and richen up the afr to sub 10.0
as far as the stumble check plugs wires opti ect.
With that amount of fuel it wouldnt be a surprise if the plugs were carbon fowled.
