No i passed it without a cat , but i run at about 1k at idle, idle not too sure id have to double check on that. But i did pass emissions hahaha who needs a cat pssh

Ok so i fixed most of my problem, heres whats left. i cant figure it out at all , but im runninf 3.75 CO's during the load, and i need to be running 1.5. Anyone got any suggestions of what it could be? Did spark plugs and wires which fixed the original problem, now its just trying to get this last bit done so i can finally pass emissions. Thanks guys

And btw it doesnt smoke at all, forgot to add that.

Thanks guys, yeah i have a 2.8l fuel injected. The emissions people told me it could be spark plugs, spark plug wires or a vacuum leak that failed one part of the emissions, and the other part that failed was the idle because it was running too rich.

I just went in to get my Z car emissioned in Arizona, and i failed. Theres most likely a vacuum leak causing the loading problems and its running rich, personally i dont know how to fix the running rich problem. Anyone wanna help me out?
