If you can see if you can have the car read to see if there are any codes that may show up to lead you in the right direction. Have you tried to clean MAF Sensor, you may want to look at your PCV valve and TPS sensor. Check to see what your fuel pump pressure is with the car running. It may be just a simple vac line that have come off or has a split in it...
