I just turned 38,000 miles on my 2005 Dodge Dakota and the check engine light came on I took it to Autozone and the said the code was P0300, definision: Cylinder misfire detected-Random cyclinders. Explanation The power train control module monitors the crankshaft speed and has detected a misfire condition..
Probable causes
1. ignition system faulty-spark plug (s),ignition wires,coil
2. Vacuum leak
3. injector fault
4. High or low fuel pressure.
I'd like to know where do I start ?

The truck is 12 years old even with the low miles will possibly need a tune up --air filter- plugs - wires-- injectors may need cleaning or their partial clogging[ possible replacement ] age and environment wear down parts and components not just mileage
P0300 Misfire Diagnostics
Before you replace a bunch of parts that don't fix the problem ,do yourself a favor an take it to a qualified repair shop that has all the tools needed to diagnose the fault .

Even with low miles, the truck has some years on it. Is the gas old? If the truck seemed to run fine, I would clear the code and see if it came back. Sometimes these things are just a one-off occurrence. If it continues, I would make sure it isn't running on old gas (if the truck has been sitting a while), then check the spark plugs, and go with the usual tune-up items.

I don't know how the above could have any effect on temperature. Is the vehicle full of coolant? In my opinion you have two different issues

I could be wrong but it sounds like you need to put some attention towards the cat and the O2 sensors.

I would check the injector. Pull the plug and check for corrosion. Use on ohm meter to check the injector. The resistance should be 11 to 15 ohms. Check it against another injector. they should be close. You can also check the injector plug. best to use is a noid light, but you can use the meter. set it to dc volts to check. the numbers should jump everytime it fires. since you got a 300 and 301 misfire it tells me that you have an intermitant misfire in cylinder 1. The other sensors are still good don't replace them. The coil is still good, because when it starts to go, it will have misfires on all cylinders or will not work at all. The crank sensor is the one that detects the misfire, again don't replace it because it's not bad, it's just doing it's job. If the injector and harness check out good then I would start check the cylinder for compression and mechanical problems
SOURCE: How are you... I have just bought a 2006 Dodge
that is the coil on top of #5 spark plug. you can replace the coil or switch it to another cylinder and see if you get a different code. misfire codes are 301-306.

2005 dodge dakota 3.7 readscode P0700 and P0300 and will barely start no power and dies PLEASE HELP ME what is the sensor i need to replace
I have had he check engine light on and reads a p300 error.
I reset with scanner and after it completes a run cycle it comes back on. The engine seems to run fine, gas milage no different. I have 30k miles on it and says to replace spark plugs. I am going to do that then see what the light does after a reset. I am not sure where to start either, but figure that plugs is one place since they are recomended to be done now anyways. For such a new truck and low miles I am a bit disapointed in RAM, my first dodge. If it is plugs not too bad, normal maintenance. Will post if it works. ANY sugestions as to what ight be a etter path to correct this?
i have a 2005 dakota and only got 22,000 miles on it and the code said it is the crankshaft position sensor
