Ya, Metro valve cover, change the oil too for reduced emissions, dirty oil
vapor sucked into the engine burns and adds HC to the exhaust. HC is also
the result of running too rich, the cat can clean it up, but if it's been rich
for a long time the CAT is probably bad too
You could reduce the HC levels with a generous dose of E-85, about 50-75%
if you can get it, in an empty tank 1 or 2 gallons should make it run clean enough
to pass the test
