My mechanic ran the diagnostic and it read "multiple misfires" He cleared the code and the problem went away. I suspect there is a lot of stuff burning off in the HFC's and CBE and the O2 sensors are trying to read things for the ECU to adjust to the new exhaust. My mechanic said to let the HFC's and CBE break in a bit and see if it throws the SES light again. But it seemed fine after he cleared the SES
Does your light flashes and what is the condition for that to happen in your case? Mine drives fine in the lower revs and bogs in the higher RPM under WOT. It seems to drive better when the engine is still cold, but after fully warmed up it is much more noticeable. It will blink the SES everytime I try to floor it to redline.
