Unhook the battery (be sure you have your radio code) for 30 minutes, and then reconnect it and do a throttle body adjustment - maybe that'll help it out. You can also try the seafoam treatment on your car (there are about a billion posts available through search on here, about how to do it).

I have done the unhook the battery thing and still have the problem I will be trying the sea foam but I'm still open to any info that someone may have thanks.

The point to the battery disconnect is to force the car into doing a throttle body alignment (TBA). Do the disconnect, then hook the battery back up, and turn the key to the full electrical power position (right before you crank the engine). If you have your hood open, you should hear a whining sound from the throttle body area of the engine - this is the throttle body resetting its position. If you did that and it didn't help, then yeah, seafoam may make a difference also, but it sounded from the post as if you only did the disconnect, and not the TBA afterward.
