Have it scanned to see if it's storing any codes at autozone or another store for free. Let me know what the codes are. But, also listen to it very closely under the hood. Often times you can hear a vacuum leak. A hose could have come unhooked, or split in half, that could easily cause what you are experiencing. Could be other things, but let me know what you get from the scan. Thanks!
