Do you have a OBD reader that you can view the live data?
That is where I would start. Watch the long term fuel trims also check the data out on what the 02 sensor is doing, blip the throttle a few times and continue to watch it, does it respond at all? If not start with oxygen sensors. Then check for any and all vacuum leaks.
