If your MAF sensor is faulty and causing your problems unplugging it will force the computer to go to a default fuel program. The car will usually run reasonably well with the MAF unpluged You can try unplugging it and see if things improve.
Most things involved with OBDII that are going to turn on the CEL and throw a code, take two back to back events over two back to back drive cycles. On the first event the computer stores the code as a pending code with no CEL. On the second event the computer triggers the CEL and throws the permanent code.
If your OBDII scanner can do it, look for pending codes. That may be a help to you. Good luck keep us posted.
