SOURCE: randome misfire on all cylinders only under load

Try putting in bosch spark plugs with the 3 electrodes ,might help .As for the code reading well i wouldnt trust that because as its a new car then the chances are its encrypted software so the code you have will not be right.If the plugs do not cure it then its dealer only and i wouldnt be surprised if it didnt end up with a new ECU unit

If you already replaced the wires, I would suggest replacing the plugs, distributor cap and rotor. They are also very important parts of the spark. Fuel injector problems can also cause misfires.

Hi.

The check engine light, driving problems and smell was in consequence of the misfires. If now the car drives fine, the vacuum leak could have been the cause of the original troubles. As far as I understood now the problem is only when idle.
Ensure that you have replaced the air filter , also double check vacuum and check/clean the air intake duct and sensors (IAT, MAP- see here for removal). Those are factors that can affect and cause misfire during idle. The IAC valve can also cause similar troubles and must be checked.

All the part listed above may cause lean or rich mixture. The problem is not necessarily detected by the O2 sensors in the exhaust and may result in no lean or rich code being stored in ECM.

If mixture and air intake are not responsible, and if the problem does not only occurr when idle, check the high voltage wires from coils to spark plugs (particularly if a code on a particular cylinder comes back). Check timing, valves, EGR and fuel pressure/fuel pump. Try doing an injector cleaning and check injectors (both spray and voltage).

Has p0300 code misfire cyl 2 and 3


If it was just cylinder 2 or 3, the code would be 0302 or 0303. Instead, you have random misfires (probably) such that you should be checking things that affect the whole engine. Vacuum leaks, bad plug wires, bad coil(s) or ignition module are most likely, but even clogged exhaust, O2 sensors and bad battery can cause these problems. Yes, a battery can be good enough to start your car but still be bad enough to affect performance. If I had to guess, I would start by testing the ignition module. Most parts stores can test this if you remove it and carry it to them.

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.

2003 Ford Ranger 4x4 extended cab- diagnostics checked and got these codes- P0171, P0174, P0300, P0316. Can you tell me what they mean?


P0171------ system too lean bank#1
Po174------ system too lean bank#2
For these 2 codes, try cleaning the maf sensor (mass air flow), that is mounted in the big black hose that goes from the air filter housing to the throttle plate, if it is dirty, that will cause those 02 sensors to send a signal to the computor to lean the air fuel mixture. If cleaning it doesn't work, the sensors will probably need changing.
P0300---- Random/multiple cylinder misfire
P0316---- Cylinder misfire at start up---- first 100 revolutions.
On those 2 codes, you have to do some testing to find out why there is a misfire.
Possible causes:
dirty/malfunctioning injectors
weak coil pack
fowling spark plugs/wires
Low fuel pressure
