I have a 2000 Dodge Dakota with a 6 cylinder motor and it has 66,000 miles on it. The last time I had a smog check the Hydro Carbons were at the maximum level. What can I do to bring these levels down to a more acceptable level? I want to make this correction before my next smog check.

Any advice anyone my have will be greatly appreciated.

Thanks,

Joe

I'd get codes read as a clue and pay a lot of attention to the routine of maintenance. Quality oil and filter, proper OE spark plugs if not done, wires if you want, high end air filter, PCV system working properly and make sure there aren't any vacuum leaks.

If there's anything about the way it runs that isn't just right chase that down. If this is a tailpipe test do make sure you are fully warmed up and a good highway run before can help especially if vehicle does a lot of poking around, short trips and so forth,

The best way to describe what HCs are is calling them "unburned fuel". It's usually not a problem with excessive fuel but with not completely burning the fuel it has. Ignition misfire is one of the most common reasons. You also want to look at things that optimize the burning process like ignition timing, compression, lean mixtures, faulty ignition components, engine temperature, etc.
