Use the SEARCH link at the top of this page, even if you have to try a few times with different word combinations to get the results you are looking for. There have been many, many, many postings on this subject. It could be one, or more, of several different things, but I would start out by running some Seafoam through the intake using the vacuum line and cleaning your MAF sensor. All of this information can be found by using the before mentioned SEARCH feature. Also, make sure the harness on your MAF is not loose.

edit: and it would help to mention if your car is stock or not
