This is probably due to a high amperage battery causing interference in the system.
If you are using an external scope, you may be experiencing vibration issues. If so you'll need to stabilize the IR beam by adding a few drops of hot glue to the 3d printed part.
If you are using an internal counter, you may be experiencing vibration issue or noise in your IR beam cable. Try adding some electrical tape to your connections on the Arduino. If that doesn't fix it, you'll need to add a .1uF capacitor between your ground and signal.
