Hi Rosalee_IM, The codes your vehicle is storing are for low voltage from your accelerator pedal position sensor and a gross evaporative emission leak. The code P2122 and P2138 are directing you to test the accelerator pedal position circuit and/ or sensor. This is the cause of the reduced power concern you are feeling.The P0455 is telling you there is a large leak in the evaporative emission system. The most common cause for this code is a loose or incorrectly installed gas cap.I hope this helps clarify the concerns you are experiencing. If you'd like more information on how to trouble shoot the problems,drop me a line. Please include the model Impala you have,(LS,LT or LTZ) and the engine size. I will do my best to get back to you as soon as possible.Thanks, Chuck
okay.how would the injectors have anything to do with the vehicle stability control/4wd.??if it were injectors at such a low mileage you would feel a real lack of power.now as toyota own diahatsu you could save yourself a fortune if you ask them to diagnose a fault!!to check vsc is working put car in 2nd and floor the pedal turning as tight a circle you can brave.it should stop the inside wheels from screaming....to check 4wd do the same and you will feel the car trying to pull itself apart.you will see what i mean.!!!
After market spark plugs could be the problem.
Reinstall the old plugs and see if that fixes it.
This vehicle has an ion sensing ignition system and is real sensitive to the proper spark plugs. I would get the proper plugs from the dealer if the old ones work.
The codes P1311 and P1312 are ion sensing codes.
Here are all the possible problems which can turn on your ABS light.

You'll need a scanner which is compatible with Hyundai's ABS system to retrieve any DTC's (Diagnostic Trouble Codes) stored in its computer. Any time the ABS light comes on, there's a DTC stored in its computer - that code will tell you where the problem exists. Then you can go from there.
