I was driving around on the freeway and the SES light started flashing and then i lost most power to the wheels so i slowed down and started heading him around halfway home the light went out and the car was back to normal ( I have no idea how) plugged in my mhd and checked codes i got the following

- DME active codes - 29CC - DME: Combustion misfires, several cylinders.
29CD - DME: Combustion misfires, cylinder 1.
29CF - DME: Combustion misfires, cylinder 3.
29D0 - DME: Combustion misfires, cylinder 4.
2C77 - DME: Oxygen sensor after catalytic converter: Signal.
2DED - DME: Power management, closed-circuit current violation.
