Rpm dropped and the car almost stalled in park. Went away and drove almost 400 miles with no problems except a little hesitation (RPM drop) one time at 70 MPH.
Did a reset of codes and came back. Codes p1603, c1424, c1422. Used a launch 129x diagnostic.

Here is what is said about the codes:

P1603: This code is related to the Powertrain Control Module (PCM) or Engine Control Module (ECM).

C1424: This code is specific to the anti-lock braking system (ABS) in a vehicle.

C1422: Like the previous code, C1422 is also related to the ABS system.

We only handle one problem per thread so you will need to start a new question for the P1603 code. Here is the instructions on how to replace the brake light switch and the right rear ABS sensor which should fix the problems. Be sure to clear the codes when completed. Check out the images (below). Please let us know if you need anything else to get the problem fixed.
