Why is my Honda Fit engine not working?
The Honda Fit is known for sudden, poor drivability issues, as soon as 50,000 miles, such as: One or more ignition coils may fail unexpectedly, even though the code may clear. The coil packs will cause engine misfires during normal operation, and must be replaced to ensure engine performance.
Can a bad ignition coil cause an engine to misfire?
Of course, because all cars are different, an ineffective ignition coil may register a different code for the problem. Alternatively, you may see a code for an engine misfire, which could be the result of a dead ignition coil. If an ignition coil is not working properly, your engine will likely misfire.
How do you change ignition coil in Honda Fit?
Swapped out one coil at a time and drove for a day (80 mile commute) until the misfire went away. One [$] coil instead of a $200+ service bill. When no codes are present, this is the same technique used by the dealership service department, except they do not drive as many miles.
What causes a car to misfire under the hood?
If you ever experience this, you won’t be able to miss it. If your engine is running lean (not enough gas in the air/fuel mixture), vehicle owners tend to blame a bad fuel injector. Before swapping those out, check under the hood for a vacuum leak that could cause a misfire.

What happens if there is no cylinder misfire counter?
If there is not a Cylinder Misfire Counter, then you might have to switch components—such as coils, spark plugs, etc.—in order to isolate the root cause of the misfire. It is also important to note and record any other codes because the engine may be misfiring due to the failure or malfunction of another system or component.
