93 civic VX failed smog. High CO
I only have 1 retest so I need to get it right. Before I retest I will:
1. Change oil
2. Change air filter
3. Swap 02 sensor for the newer one I have laying around
4. Clean Egr valve
5. Change spark plugs. I already have a new distributor and wires
That's all I can think of for now. What else should I do before the next retest?
I'm only 0.01 points from passing so I don't think I'll have to do anything major like replace the catalytic converter

HC is rather high as well. I'd look for a rich condition. Check that the fuel pressure compensator vacuum line is hooked up. Take out the spark plugs and look for one that is darker than the others.

Ok I don't know what that is but I know I have a vacuum leak and an oil leak on the oil pan. Where is that vacuum line exactly? Also i forgot to mention new spark plugs are on the way. Editing op post
