Jeep liberty code po300


po300 is Random/Multiple Cylinder Misfire Detected.This means the PCM sees misfires on more than one cylinder,so it's probably a fuel issue.You might have a bad fuel pump(bearings are binding,causing low fuel volume).It could be the in-tank filter is plugged up,or maybe the in-line filter.Start with the easiest-the in-line filter.

2005 Jeep Liberty has hesistation after it warms up. Code says misfire cylinder 4 replaced coil, wires, fuel pump, fuel filter


Check injector pulse to make sure the computer is commanding the injector on and off. Check that the plug isn't cracked. Check cylinder compression if all ok you may need and injector but you could probably try an injector cleaning service( not the stuff you throw in the tank)

Rough idle random cylinder misfire


misfires are more from problem injectors, low fuel pressure or injector wiring than from plugs
have a fuel pressure test done to check for problem pressure regulator , problem fuel pump , blocked m/dirty filter
one other area of concern is the EVAP system where the purge valve doesn't vent the tank properly and causes low fuel flow rates
