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.

i just pulled them out and there fine! why is reading this? and that was the temp on startup, if its reaching 2000 F. could this severe retard my engine?

Car will also pull I believe close to 6-8 degrees of timing.

Don't think it'll flood the motor THAT bad.
