P2302 Ignition coil 1 secondary circuit -insufficient ionization

This type of code will not cause a Limp mode,what this code mean is the burn time is too short, this can be from incorrect sparkplug application.or faulty coil. When there is a Limp mode or fail safe this is due to the TPS (throttle positon sensor) correlation . which can be caused by vacuum leaks.
