Hey guys,
I recently had my car tuned with HPtuners and a HSW nitrous kit put on. I had to tap into the first 02 sensor before the cat to get it to work, and now the rear 02 sensor is acting funny. The codes I get are
P0420 - Catalyst system efficiency below threshold (bank 1)
P0410 - Secondary air injection system malfunction
My mechanic friend says its b/c i beat it like a red headed stepchild, and all the extra nitrous and fuel that goes into my cats is clogging the cats up...
I have nick @ HSW looking over this.. but also wanted to know if anyone had any advice/suggestions about this stuff. I was forever plagued with P0420 when i had put headers on my 5.7 HEMI, now im having this trouble with the camaro! It never ends!!!
Thanks a million everyone!

I just took it to oreilys auto parts to have the codes cleared off and on the way home the codes IMMEDIATELY came back on... what gives with that?
