Experiencing a rough idle or engine miss in your vehicle can be concerning. Before you start replacing parts, an Obd2 Misfire Counter App can be an invaluable tool for diagnosing the issue. Using an app like Torque Pro, paired with an OBD2 adapter, allows you to monitor your engine’s misfires in real-time, pinpointing potential problems without even popping the hood. This guide will show you how to use an OBD2 misfire counter app to get to the root of your engine troubles.
One of the most effective and budget-friendly ways to monitor misfires is by using an OBD2 app on your smartphone or tablet. Torque Pro, a popular app for Android devices, offers robust diagnostic capabilities, including real-time misfire monitoring. To get started, you’ll need the Torque Pro app and a compatible OBD2 adapter that plugs into your car’s OBD port, usually located under the dashboard.
Once you have Torque Pro set up and connected to your vehicle, navigating to the misfire monitoring feature is straightforward. From the Torque Pro home screen, select “Test results.” It’s crucial to keep your engine running and wait patiently on the “Test results” screen for a few minutes. This allows the app to communicate with your vehicle’s computer and gather the necessary data. Avoid navigating away from this screen during this initial loading period.
After a short wait, you’ll be able to scroll down and find the misfire test results. Look for “test 53,” which represents the misfire tests. Torque Pro breaks down misfires by cylinder, identifying each cylinder as CID:$01, CID:$02, CID:$03, and so on, depending on your engine’s cylinder configuration. This cylinder-specific data is incredibly useful for pinpointing which cylinder might be experiencing issues.

For a broader overview, Torque Pro, in conjunction with the free “Torque Scan” plugin, can display the total number of misfires. Similar to the cylinder-specific test, access “Torque Scan” and allow it time to load the data without switching screens. This plugin presents a comprehensive list of vehicle data, including “Total Misfire Count.” Keep in mind that the “Total Misfire Count” typically reflects misfires within the current drive cycle only and will reset when the ignition is turned off or codes are cleared.
To effectively diagnose intermittent issues, it’s helpful to monitor misfires during a drive. Start Torque Pro and navigate to the “Test results” screen before you begin driving. Leave it running as you drive, and then check the results when you reach your destination. Switching to “Torque Scan” on your return trip can also provide valuable data. Having a passenger assist with monitoring the app while you drive ensures safety and allows for real-time observation of misfire counts under different driving conditions.

Understanding the visual cues in Torque Pro is also key to interpreting misfire data. A green check and highlight next to a cylinder misfire test indicate that data is being reported and that the test passed, meaning no misfires were detected for that cylinder according to the OBDII system’s thresholds for setting a fault code or Check Engine Light. Cylinders without misfires are typically shown with a static black background and no highlighting, indicating normal operation. This distinction is valuable because knowing what is not happening is just as important as identifying problems. Parameters that your specific vehicle doesn’t monitor will also appear with the static black background in Torque Scan.
Using an OBD2 misfire counter app like Torque Pro offers a cost-effective and insightful approach to diagnosing engine misfires. For a minimal investment in the app and an OBD2 adapter, you gain access to professional-level diagnostic information, empowering you to troubleshoot engine issues methodically and efficiently. This tool eliminates guesswork and helps you focus your repairs where they are truly needed, saving both time and money.
