SES light on, clogged cat converter...

On my 96 K1500, 5.7, the SES light came on and noticed a horrible burning sulfur smell coming from exhaust, not to mention the huge loss of power, pulled exhaust off to find cat almost completely clogged, any way to fix without buying a new cat?...

Re: SES light on, clogged cat converter...

No. The catalytic converter is a emissions device that is used to have the vehicle meet federal emission standards. The vehicle will not pass your state inspection if it is removed.

What you need to do is find out why the catalytic converter failed.

If you don't fix the engine emissions issue, the catalytic converter will likely fail again.
