I searched around a bit and didn't turn up anything I thought was similar to my situation. Maybe I'm just really new to all this but I've had the p0410 code for some time now and haven't gotten to fixing it yet. I have to get my emissions test done soon but can't with the code on. So me being a bright guy I decided to clear the code, when I did this I noticed I have 2 more codes p0422 and another bank as well.Could the secondary air injection system problem be hurting my cats or is this just a whole other problem that I need to address? Thanks in advance for quick replies. Aaron
