That there ya got is a code 67, or P0420, the dreaded catalytic converter code.
Thanks james'99, that's what I was suspecting, but the time between the first and 2nd blink seemed a little different than the time between the 2nd and 3rd blink, so I wasn't quite sure.

I have some cheap ebay headers that have been on the car since I got it, It's throwing P1165, I relocated the 02 sensor to the bottom of the downpipe hoping that would fix the air/fuel issue, cleared the code and it came back on after about 20 minutes of driving, need to get it gone so I can pass emissions, any suggestions

Hey guys. I was going to make an intro thread but then this happened. Driving home from work, my CEL comes on. I paperclipped the switch and a got 70 & 90. No big deal, I get that. Now I look over to the D4 and it's giving me 25. I can't find tcu/tcm codes anywhere! I'm pretty far out from an autozone right now so Im wondering if I can self diagnose.
