03 jeep liberty

Engine light comes on when going down hill, at times will go into limp-in mode, until stop engine and restart. Codes are,Po 300 Random multiple cylinder misfire. 301-303-304-306. Engine is good otherwise. Thanks

lovette, it would have been best if you went back to your original thread:

Just go there and provide an update on any new info or attempted diagnostics/repairs.

Are you saying that the transmission goes into limp mode in addition to the misfire?

The light will flash, even when it is on, when going down hill. Often it goes into limp in mode when this happens. The jeep does fine until this happens.
