SOURCE: po300 multiple cylinder misfire po705 transfer case circuit malfunction

Check the EGR valve. Replacing the EGR valve fixed my error code for misfiring. I also had to remove the battery cable for 5 minutes to turn off the check engine light.

SOURCE: 2000 CIVIC System too lean Cylinder 3 and 4 misfire Deteced

  1. P0171: This means that the oxygen sensor has detected a lean air-fuel ratio. This can be caused due to a vaccuum leak or a problem in the HO2S circuit or the HO2S (Heated Oxygen Sensor) itself. (Bank one Sensor one). This is commonly located along the exhaust pipe. It could also be a bad Mass Air Flow sensor or a bad Engine Coolant Temperature sensor. Diagnostic checks will be needed to be carried out to be verified though
  2. Well as for the other codes, it means #3&4 cylinders are misfiring. It is a possibility that the P0171 code mite have caused the others to show up. I can be wrong though. But it is a strong possibility. If the air fuel mixtue is too lean indeed, mis-firing will occur, unless it is an actual electronic and not a mechnical problem. By the way, when these codes appear, how is the engine's performance. Does it remain the same or behaves poorly?

SOURCE: random/multiple cylinder misfire

if you have done the basics of replacing plugs and wires,
what I found on a dodge that was doing the same thing,
I could watch the misfires happening on the scanner but the engine wasn't missing,turned out to be dirt and things floating in the fuel rail and partially plugging the screens on the injectors.

SOURCE: 2006 RAV4 V6 multiple cylinder misfire, VSC, check engine and sli

You need a scanner to pull out the engine light codes.
Use a shopu manual to aid you with the diagnosis and repair.
The slip indicator and vsc light being on means these systems are not working. Once you pull the codes and do the repair and erase the codes the lights will go off.
There will be a code in there for the misfiring.
Good luck and keep me posted.

SOURCE: My C230 Mercedes has check engine light on. Car

P0171 indicates a lean condition. The most common cause of this is a defective mass air flow sensor. Also check if any vacuum leaks.Replace MAf sensor,if cleaning the MAF does not help.
Thanks.

When my car is ran on computer is has cose PO300 PD. What does this indicate?


DTC P0300 - Random/Multiple Cylinder Misfire Detected
Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.

A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.

Hope this helps.

Multiple cylinder misfire


There could be a couple of reasons for this. If you are getting multiple misfires then usually it has something to due with the plugs going bad. It also depends on how many miles you have on the plugs and the wires. The other problem could be with the ignition coils or the ignition module.
