if it otherwise drives fine it's usually emissions related.
in any event, you'd need to have the codes pulled to find the specific issue.
most any auto parts store will do that for you for free in about two min. they *may* give you a generic explanation of that code. so one would need to look the code up using a model specific chart.
that chart can be found here,

hope that helps!
