Codepo300andcodep3400


P0300 is a misfire on any cylinder and P3400 is variable valve timing deactivation error. You did not post the make model and year but the 3400 would cause the 300.

2005 Buick Las 4 door Code p0300


Not much.
Code 300 is for a random miss. The engine computer has detected more than one cylinder that is not producing power, but no one cylinder is constant.
Until you get a code like 301 or 303 its a guessing game. 301-306 would tell you which cylinder is being the problem.
The cause could be fuel or spark.

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.

P0300


Im assuming your asking about the ODB-II codes, this code,P0300 Random/Multiple Cylinder Misfire Detected.
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.
Here are a few things that could be the cause.
  • Faulty spark plugs or wires
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector(s)
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Stuck/blocked EGR valve / passages
  • Faulty camshaft position sensor
  • Defective computer

    I would start things out with a tune up, new plugs and wires, wires break down after time and could be grounding out, or arcing between themselves causing a misfire.

    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.
