What do these codes mean together?
Paste the list of codes your scanner gave you. We explain each one and — more importantly — what they mean together: several codes often come from one cause.
Paste anything: a list with commas, lines copied from another app, words in between. We will find the codes ourselves.
What they have in common
This is the part a per-code reference cannot tell you.
Several cylinders misfiring at once usually means a common cause rather than several dead coils: fuel pressure, the mixture, bad fuel, or a timing shift. Replacing plugs one by one here is the expensive way round.
Each code
Misfire in several cylinders at once. Spark plugs, coils, air in the fuel. Do not drive long with this code: unburnt fuel kills the catalytic converter.
Misfire in cylinder 1. Usually the plug or the coil — swap them with a neighbouring cylinder and see whether the code moves too.
Misfire in cylinder 2. Swap the plug and coil with a neighbouring cylinder: if the code moves with them, the part is at fault, not the engine.
How to put together a report a mechanic will actually read
How this usually feels
Signs that match more than one code from your list — the readings under each one narrow the search further.
How the app helps
CarScan reads these codes from your own car, shows whether each is active right now or only stored, adds the live readings behind them and puts everything into a report for a mechanic.
