The first thing you want to check is the fuel pressure using a fuel pressure gauge. Low fuel pressure will act that way although I really don't expect you to find low pressure but it needs to be checked. If you can confirm good pressure, then I would look at the Mass Air Flow sensor. Sometimes you can try unplugging it and the computer will see it gone and go to default settings. If you see a major improvement, then I would replace the sensor.
