If you replace the Catalytic Converter with a straight pipe on a 2002 Chevy Blazer 4.3 with 112000 miles, how do you stop it from throwing the Check Engine light without affecting other check engine signals?

Do you
have the same problem?

Removing the catalyst from a vehicle is illegal and punnishable by hefty fines or jail time.I dont think anyone is going to be able to help on this one. Sorry.

It's illegal. Besides, it will throw codes because the back O2 sensor checks emissions and adjusts fuel etc from that data.
