emissions issue need help asap
88 civic hatch, 1.6 liter motor with stock tune, new cat new charcoal canister, new purge valve and map sensor
did new autolite spark plugs and put 16 oz of denatured alcohol and a few gallons of gas giving me a 1/4 tank and failed worse previous scores were hc 1.14 pass, co 15.24 fail, nox 1.55 pass
current scores hc 2.06 fail, co 51 fail, nox 1.33 pass
only changes from that run to this one were spark plugs and ethanol

Re: emissions issue need help asap
I'd put the Honda reccomended KGK-R plugs, gapped correctly, back in there.... ditch the alcohol, do new HONDA cap and rotor as well as retard the timing.
First do compression and leak down tests to check the health of the internals.
