Whats causing a p0300 trouble code on 1996 dodge caravan 3.0L?

SOURCE: Engine light comes on - Code shows P0300 and then

OBD II 300 Random/Multiple Cylinder Misfire Detected

When the misfire monitor detects a misfire, it will trigger the check engine light with the specific cylinder number as the last digit in the P030X code. For instance cylinder 1 misfire is P0301, cylinder 2 is P0302 etc. In this case we have either multiple cylinders misfiring, or the computer simply can't determine the specific cylinder, and as such we are left with the P0300 in computer memory.

Possible Causes:

Fuel injectors, related wiring, sensors and computer issues
Running out of gas, or poor fuel quality
Evaporative emissions system (EVAP) concerns: fuel vapors leaking into engine
Incorrect Fuel Pressure
EGR system concerns: leaking EGR valve or restricted ports
Base engine concerns: low compression, valve train problems and timing issues
Ignition system concerns including, but not limited to:
Faulty spark plugs
Faulty coil or related wiring
Ignition module or related wiring issues
Ignition related sensor faults or wiring issues

SOURCE: what do fault codes 12, 21, and 55 mean on a 1996

Code 12 = unplug battery recently (allways appear this code)
Code 21 = O2 sensor (the way to solve is replace it)
Code 55 = finish test

Good luck (remember comment and rated this post).
