FYI, no dice on the Catclean as halfway suspected and halfway hoped.
While the numbers on the data stream still look better, Check engine keeps coming back with same 0420- 0430 codes. Guess I'm still looking at the inevitable replacement of the Cats in order to properly fix this.
Looks like not too difficult of a swap. luckily someone engineered this section to bolt in and can be done in the driveway. What i'm wondering now is, what quality do I need to run with? They really range in price and I only want to do this once.
