Smog



I have a 94 four runner v6 that i just had to get smogged it passed but my hydro carbons at idle and running rpms are high and almost the same. Any idea what could be causing the high hydrocarbons?

Rebootej,



The important thing to remember here is that it passed smog. Hydrocarbons are a result of incomplete combustion. You can run lower octaine gas that will burn faster and cleaner. You can change your air filter and put new spark plugs in, if it is a real concern. Hope this helps.

The thing that won't cost any extra money is the fuel.
