Hello. I recently bought a 2000 gle about a month ago and after driving it for a couple weeks about 1000 miles highway. The ses light came on and mpg was very low checked and it was the dreaded p0430 code which i believe is for the bank 2 cat well yesterday while driving on take off i lost power and it gradually increased with the more gas i gave then srs light blinking rotten egg smell then ses light went back to a steady on please help

 

replace or remove the cat. What else do you need help with?

 

Which cat there is 3

 

Remove them all or replace all. Seriously. If a precat fails, it will ruin the cat under the car, The precats are on the manifolds.. Just grab some headers off ebay for $100-200. You can add a new cat under the car for inspections if you need to.
