What Is Misfire Data?
What Is Misfire Data? (And Why Autel Makes It Easy)
If your car feels rough, shakes a little, or just doesn't have the power it used to, it might be misfiring. But don't worry—modern scan tools like Autel Scanner make it super easy to check what's going on under the hood.
So, What Is Misfire Data?
Every time your engine runs, it's supposed to fire each cylinder in a specific order. If one of them skips, hesitates, or fails to fire—that's a misfire.
Misfire data shows you:
- Which cylinder is misfiring
- How often it happens (called misfire count)
- If it's a current or historical issue
Why Does It Matter?
Misfires can cause:
- Reduced engine performance
- Higher fuel consumption
- Failed smog or emissions tests
- Long-term engine damage if ignored
How to Check Misfire Data (The Easy Way)
The easiest way to check for misfires is with an OBD2 scan tool. We recommend using an Autel scanner, especially for beginners.
Why Autel?
- User-friendly interface—even if you're new
- Live misfire count per cylinder
- Works on most vehicles
- Affordable options like MK808BT Pro, MP900, or MS906 Pro
Here's What You Do:
- Plug the Autel scanner into your car's OBD2 port
- Go to Live Data or Misfire Data
- Check for any cylinders showing misfire counts
If you see one cylinder misfiring repeatedly, it could be a spark plug, coil, injector, or something else that needs fixing.
Final Thoughts
Don't let a small engine shake turn into a big repair bill. With an Autel scanner, even total beginners can quickly read misfire data and start solving problems.
