'87 RC--318 2B--High Carbon Monoxide

Hi Everyone...

Emissions Test here in Texas failed my baby today :-[

Everything is good except carbon monoxide at low idle (706)...my reading was 1.97 and it needs to be 1.20

Any suggestions?

Prior to last year's test (my first with my RC) I did the plugs, wires, cap, rotor and it passed...only put on 8k during the year. Is another tune up in order? I will pull a plug when engine cools...just got back...

Thanks All!

Well it seems like a hot engine will pass more than a cold engine does . I know using some sort of additive i can't remember what it is . Also make sure u r cat converter is in good shape .
