Multiple misfire across all cylinders indicates either a systemic electrical fault such as coil or crank sensor failure or it could be that the car is running excessively lean causing a very hot ignition and spontaneous ignition (misfire) events. The lean burn could be due to a failed exhaust gas recirculation EGR valve or a blocked passageway leading to the EGR valve. Go with the crank sensor first as this is most likely not to be recorded as a separate fault code.

Random/Multiple Cylinder Misfire Detected.

You should probably check your cylinders. Is your vehicle making a putt putt sound?

Hooked up computer to dodge ram 1500 4.7 liter magnum code came up p300 p301 what does this mean


P0300 is the random misfire code. P0301 is the misfire code for Cylinder #1. When was your last tune up? non platinum spark plugs should be replaced around 30-60k along with the wires. With platinum plugs that extends out to 100k. I would try a tune up first plugs and wires. Reasonably cheap fix that is a prevenitive maintenace item anyways. If you have just recently had a tune up or it does not solve your problem you most likely have a bad coil pack on cylinder#1.

Hope This Helps.

2004 Saturn, "L" series, 3 liter V-6. po300,


300 is random misfire and 306 is cylinder #6, I would check the coil pack on #6. If it has separate coils per cyliner, swap the coil, see if the misfire goes to that cylinder. If it does replace the coil.
If it has three coil packs you can still swap the coils. If that doesn't fix your problem, then you will have to check the injector with an ohm meter. resistance between the prongs should be between 11 to 15 ohms. check another injector and they should be relatively close. Let me know
Good luck

These are misfire codes.This means that your vehicle is missing.The 300 is a random misfire and the 305 is for cylinder 5,and the 306 is for cylinder number 6.Check the plugs if they are good then you could have bad coils.They are top of the plugs.Hope this helps.Good luck.

Random misfires are some of the trickiest problems to solve, usually an ignition system problem a bad or weak coil pack or possibly a spark plug wire. If not the ignition system then surely a clogged injector.
