MISFIRES CODES

2002 Dodge Caravan

Engine Mechanical problem
2002 Dodge Caravan 6 cyl Two Wheel Drive Automatic

Hello there I am having probles with my caravan. All of a sudden one morning I tried to start the car but would not start (cranked fine and had gas) I changed the crank position sensor, and got it to start but the noticed a miss in the engine I the but a reader on it and got codes 300,302,304 which are misfire codes. I checked the plugs and plugs wire (seemed ok). My next thoughts are that it might be the cam position sensor? What is your advice Thanks

Engine misfires can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.
