Check engine soon

[aero993]

About 1 week ago my check engine soon light came on. Today, I went to pass a car and could go over 50 mph. I think that my cat converter might be clogged. Is there a fault code that signals a clogged converter? I will try to have the fault code read tomorrow. Truck is an 01 Tahoe with 155k miles. Any other possibilities or suggestions?


TIA,

Anthony

The codes read bank one and two o2 sensor. Drop car off at a local shop. I was told what I expected bad cat converter. They installed new cat from the stealership and all is well. The codes cleared, they didn't have to install o2 sensors also.
Thanks

The code read bank1 and bank2 below acceptable level? Or bank1 and bank2 indicate lean? If it was the latter, I think your code will be coming back.
