So, my CEL came on.

[pandaudi]

The culprit was the rear o2 sensor/ catalyist efficiency due to the test pipe. Hooked up an obd-II reader to erase the code. Then I started, my car started bogging and dying. Did this 3 times before I hold the rev at 2k. Then no cel after driving.

Sigh. I guess I'm gonna get flashed.

Btw, I'll also post here everytime cel comes on by how may miles I traveled.

Cel came back on within 50 miles

[aaaudiprotein]

your best bet is to get read the codes first

What was the outcome?

^^^^^from 15-30 miles, I would get CEL. Even if I drove long distance. This was with the anti-fouler that I used. Maybe I didn't drilled it correctly or anti-foulers didn't work.

Well it's gone now since I have flash.
