If the initial timing is adjustable, retard it 6-8 degrees from spec. If it has an EGR system, check it for proper operation.

You don't need fuel injector cleaning, and idle speed has little or no effect on HC or CO emssions on the IM240 test, and NO EFFECT on NOx emissions.

Visit the current emission discussion threads for some more insight. They're obvious from the titles.

Your car was tested on a device called a chassis dynomometer. The term "treadmill" is used by state bureaucrates who think the people who pay their salaries are idiots and can't understand "big words".
