When the vehicle goes into limp mode when the engine misfires, the computer is shutting down the electronics to the transmission to prevent damage to the catalytic converter as the fuel condition is either too lean or too rich. Check the spark plugs to see if they are firing and if they can produce a strong spark. If the spark plugs are not firing, then they would need replaced or the coils need checked for spark and power to them.
If the spark plugs are working, then check the fuel system and see if they are firing correctly.
A fuel injector could be dirty or leaking causing a lean or rich fuel condition. I suggest putting a fuel injection cleaner in the fuel system and cleaning out the system from buildup and to help with the injectors.
