Check engine light on again...

[TexasSnake]

I have taken my car to my tuner 4 times to have the check engine light turned off and it is back on again. This time it lasted about 30 minutes before coming back on (a new record). I know it has to do with the cat deletes. My car was tuned with the SCT tuner. Can someone please direct me to an answer of how to eliminate it from coming back on?

Thanks...

If you are certain that the cause of the check engine light is due to having the cats removed, then I'd call up Sean Roe, they are supposed to be able to turn off the rear O2's so your computer doesn't even think they are there.

Are the 02's plugged in? They need to be with the SCT even if coded out.

If necessary, you can buy O2 simulators for the down stream O2 sensor and just plug them in, a very easy fix.
