Yeah , take it to a qualified repair shop.
Anything from bad connections, wiring, pins at module connector and the module itself can cause this to happen . As Jeff said a professional technician will be the best choice .

Some K&N air filters are an "oil-soaked" filter and it is that oil that can cause the problem you are having. If you want to be sure, remove the filter, clear the code(s) then drive the car. If the code(s) do not return, install a non-oil-soaked filter.
SOURCE: can I clean my Maf sensor and throttle body myself
Yes it will help car run better. Take off any hose that goes to card so that you can see down throttle bore. Start car. Grab throttle linkage and figure out how to move it so that you can make the engine go faster. Begine to spray inside throttle body using little red hose that came with carb cleaner. While you are spraying the engine will try to cut out move the throttle linkage to speed up the engine so it won't cut out. Keep spraying all around inside and outside throttle bore.

SOURCE: clogged egr valve cause
Several things can cause the engine power to be reduced. Yes, the EGR valve can affect and reduce the engines power if it is stuck open (even just partially). The valve must be in the closed position. and will open as the ECU decides to. P2138 can refer to the TPS but can also refer to the throttle pedal. Is the throttle pedal electric or does it have a cable? If it is electric then you also would need to inspect TAC unit. I hope this helps. If you have more information and or details please let me know. Good luck.
It's a sensor/switch down on gas pedal. Go to dealer order one it's artached by two bolts and an electrical plug

Did that yesterday AMD after already putting 500 in this car I'm not willing to pay 90 an hour. Trying to fix on my own but thanks for the advice.
If you have an oscilloscope you can test the integrity of the circuit signals .
And a good scan tool with bidirectional abilities to activate the components to test them with the oscilloscope .
