[ma-serca] Failed Emissions Follow Up (long)

[Gene Kwon]

	Put some of that engine cleaner jonks in your gas tank too. I
think a high NOx means you are running lean, which cleaner fuel injectors
will help. This is a quick fix and cost about two bucks. You will burn off
all sorts of crap while you are feeding your engine this crap so best to
wait till after a tank of gas. Also I hear it is generally a good idea to
change you oil after this too as the purging process can dirty your oil
quicky too.

	BTW, retarding the ignition means it is sparking sooner... thus
giving the cylinder more time to burn? Was that your plan?
