P0300 Code 06 Durango 4.7 AWD
Im getting a P0300 code on my durango, a little back ground i was getting a cam shaft position code and a crank shaft position sensor code i changed both sensors and the codes fell off when i got them checked again i only had one code left and it was a a cataylis defficecy on Bank 2 sensor O2 sensor i changed the o2 sensor which was a bitch to get out and replaced it with a autozone bosh 02 sensor. The next day i turned on my rango and it would start chugging and was loosing a ton of power after i got it above 1500 RPMs it would smooth out or i couldnt feel the chugging anymore. I have had the Vehicle for around two years started with 60,000 miles now has 80k dont no if the plugs were ever changed. Can anyone give me some ideas or help me i don't know if im just wasting my time replacing parts i may or may not need. thanks.

While I cannot diagnose on the forum, I can at least give you the P0300 description. See below.
P0300-MULTIPLE CYLINDER MISFIRE
.- When Monitored: Any time the engine is running, and the adaptive numerator has been successfully updated.
- Set Condition: The threshold to set the fault is application specific; it is tied to the level of misfire that will cause emissions to increase to 1.5 times the standard or in some cases 1%. It is always a two trip fault above the calibrated RPM. It takes 1 soft fail to set a malfunction and two trips to set the MIL. Three good trips to turn off the MIL.
Possible Causes
(A955) ASD RELAY OUTPUT CIRCUIT
INJECTOR CONTROL CIRCUIT
COIL CONTROL CIRCUIT
SPARK PLUG
IGNITION COIL
FUEL PUMP INLET STRAINER PLUGGED
RESTRICTED FUEL SUPPLY LINE
FUEL PUMP MODULE
FUEL PRESSURE LEAK DOWN
FUEL INJECTOR
POWERTRAIN CONTROL MODULE (PCM)

Thanks
Thanks for your help, I tightened up the gas cap and the vehicles shaking went away but still is not quite right. I will be changing the Spark Plugs tomorrow. Im using champion spark plugs because that's what it came with. Ill let you know if there is any change if not im going to spend the money and have it diagnosed because im moving in a few weeks.
