Automotive RepairDiagnostics & Troubleshooting3MediumOwner$ implied

A mechanic needs to confirm whether intermittent misfire and dash light issues on a 2018 Honda CRV 1.5T are caused by a head gasket leak between cylinders 2 and 3, lacking experience with this engine pattern.

Existing diagnostic tools and techniques (code readers, coil swaps) fail to definitively confirm a subtle head gasket leak that only manifests under cold start conditions and leaves ambiguous coolant staining.

Workarounds Described

lets car sit overnight to inspect spark plug holes for coolant staining with phone camera
moved coils around to see if misfire pattern changes

Implied Software Gaps

Image recognition tool that compares cylinder stain photos to known head gasket leak patterns
Cold-start misfire analysis tool that correlates sensor data to cylinder-specific coolant ingress without manual interpretation

App Concept

GasketSniff Diagnostic

An AI-assisted diagnostic app for mechanics that analyzes cold-start misfire patterns, cylinder staining photos, and engine data to pinpoint subtle head gasket leaks on modern turbo engines. Combines image recognition of coolant stains with real-time misfire waveform analysis to provide a confident diagnosis without teardown.

Key Features

Photo-based stain pattern recognition with confidence scoring
Cold-start misfire data collection and analysis against known failure models
Step-by-step diagnostic tree for intermittent head gasket leaks
Community-shared case library for uncommon engine patterns

Target Users: Independent auto repair shop owners and technicians diagnosing complex intermittent engine issues on modern vehicles

Revenue Model: $19.99 per diagnostic report or $49/mo subscription for unlimited use
