Answers :

The cause of the high hydro carbon may be due to unburnt fuel that comes out of your exhaust. This does not mean you have to replace a part. I suggest to start with the simple things, like ensuring that your car is breathing and running correctly. Start with cleaning the air filter, ensure that there are nothing that restricts air. You may want to check on your oxygen sensor if it is still working properly. The oxygen sensor helps determine the mixture of gasoline and air. Check out your spark plugs, you should have a light brown like color on them. Otherwise you may not be burning the fuel correctly.

For other issues that may have caused it you may experience some changes with how your car runs, like not idling properly, etc. May be caused by another engine part that in turn caused the high emission. Advise if there are changes in your car which may give us additional clues.
