What does this mean?
OBD2 Code P0300 Infiniti Definition:
Basically this means that the car’s computer has realized that not all engine fat is shooting properly. The P0300 Infiniti notification code indicates easy or various damage. If the last number is a zero number, it equates to a strong number which is confusing. The P0302 Infiniti code, for example, may tell you that the second number of cylinders is faulty. Unfortunately, the P0300 Infiniti does not tell you exactly which cylinders are firing incorrectly, or what.
Possible indicators of OBD code P0300 Infiniti
the engine may be difficult to start the engine may crash / break down, and / or suspect other symptoms may be present
What could cause the OBD P0300 Infiniti code
Code P0300 Infiniti could mean that one or more of the following have happened: Wrong plugs or wires Wrong inputs (packages) Wrong (oxygen) Fuel supply (s) Burning valves Downloading faulty converter Fixed / closed EGR valve / verses Wrong Camshaft computer software Wrong computers
If there are no signs, the easiest thing to do is to reset the code and see if it comes back. If there are signs such as that the engine is failing or slowing down, look for all connectors and connectors that lead to the plugs (eg plugs). Depending on the length of time you spend on car accessories, it may be best to adjust them as part of your maintenance plan. I recommend plugs, plug wires, split cups, and rounds (if possible). Otherwise, look for coils (aka coil packs). In some cases, the support switch has gone wrong. If you are smelling hot eggs, your cat converter should be changed. I have also heard from time to time that the problem was with the wrong fuel. Errors of any kind that jump from one cylinder to another (read: Code P030x) will reset the P0300 Infiniti code. The cause is usually a thinner oil, which may be the result of a residual discharge of excess or light gas that passes through an air conditioner, or an open EGR valve.
