I went for my E-test today and didnt do any of the standard prep work for it. No oil change, plugs or wires. And I failed quite bad.

2500rpm
Limit Reading Result
HC 200 107 Pass
CO 1.0 1.33 Fail
NO N/A

Idle
Limit Reading Result
HC 200 208 Fail
CO 1.0 2.53 Fail
NO N/A

Now I will go change my plugs, my wires are still in good condition. I am running stock injectors and fuel system with a DSMlink.

I have been thru just about every thread there is on e-test and all the of them almost conflict each other.

Any pointers? Looks like I am running way rich at idle. Also does running 84 octane gas help or hurt? Currently I am running Ultra94 only
