How RootCause approaches a code like this
A misfire code in particular doesn't point at one part — it means the engine detected a cylinder not firing cleanly. Ignition, fuel delivery, compression, and even a vacuum leak can all trigger the same code. RootCause gathers evidence — prior repair history, live sensor data, targeted tests — and ranks what's actually wrong before you spend on a guess, with an honest list of what the evidence argues against.
