Intermittent misfire on a specific cylinder (P0301) that only manifests during long-distance towing, making diagnosis difficult because the problem cannot be triggered locally.

Workarounds Described

• swaps ignition coil with another cylinder to see if misfire moves

Implied Software Gaps

• A diagnostic tool that logs misfire conditions over time to enable remote diagnosis without needing to physically swap parts on the road

MisfireSnap Diagnostic Logger

A plug-and-play OBD-II dongle that continuously monitors cylinder misfire counts and engine load. When a misfire is detected, it logs the exact conditions (RPM, load, temperature, duration) and sends an alert to the user's phone. Review the data to pinpoint whether the issue is coil, plug, or fuel-related without needing to reproduce the problem on demand.
