No cat, how do you keep the check engine light from being on all the time.

When i cut the cat out i took the o2 sensior out of the cat and welded it back into the exhaust so it still reads as it being there- gonogo (Jan 02, 2012 1:13 pm)

Can't be reading right with no cat, should put check engine light on if in fact the check light does work.

NO the check engine light works because when it was missing on one cyl. it came on after i cut the cat out it just runs a little bit fatter now- gonogo (Jan 04, 2012 9:13 am)

Well the post cat sensor sends information to the PCM on how well the cat efficiency is performing . No cat, poor performance, light on. Well who am I to say your light is on.
BTW you can buy a sensor to plug into the 02 sensor and the PCM still thinks there is a cat installed. I would never do it though.

I will just leave it alone it doesn't turn the check engine light on and it still runs great no problems i acutally think it running a little bit fatter helps it in the long runTo POST a message, please
