I have intermittent engine codes on my HHR. They are P0013 & P0014. I know what they are but I don't know what to do about it. If I have to do it I will take to Chevy dealer but that is my last resort. Thanks for any help given and Merry Christmas to all.

 

I moved this to it's own thread. Tacking onto the end of a thread devoted to defining engine codes does not get you noticed.

The first thing you should do is type the code into Google, then follow a few of the links. This will get you an understanding of what you are up against.

And then type the code into the search box top center of each page on this forum. There is at least one very detailed how-to article on the usual fix.

and several other threads about the codes.

 

X2 on what donbrew posted.

Fwiw. When posting questions about your car, it's best to include the year, engine size and mileage.
