How's it going everyone? Well I tried to pass emissions again here in Colorado and FAILED again. I have 2.85 CO readings when 1.50 is allowed (at 2500 RPM). My Idle CO passed with .01 which is really confusing to me. I don't know where to start, but these numbers are with a new O2 sensor and the guaranteed to pass stuff. I am thinking about looking at the timing even though I haven't touched it at all...Also I was wondering if I need a new Catalytic Converter. I also have a new distributor, cap, rotor, and plugs but I'm pretty sure that's not the problem...Please post if anyone could help...Thanks
