Hey everyone! So basically i failed smog today..turns out my timing was at 35BTDC instead of 5btdc so i failed on that. Next i passed everything except N0x which was 3 times the max. So basically what i did before the test was change my thermostat to a hotter one because i heard that would help the cat work better and put on a new cat, but after figuring out high n0x is from high CC temp i feel like that was a bad idea. So what do you guys think i should do? I was thinking about just setting my timing to manufacturer's specs and putting in a cooler thermo to lower my n0x. My egr system is working fine and my 02 should be good although i was burning some oil for a while. I dont know about MAF or how to test it. Should i try to "clean" my 02 sensor? Any tips or what you guys would do would ve extremely helpful. Also i only have 7 days to smog it before my temp oper permit is expired...which sucks.
