An 1989 Firebird with fuel injection won't idle properly with the MAF sensor connected, and runs in limp mode with weak power when the MAF is disconnected, after sitting for years and numerous part replacements.

The owner has replaced many parts and tried trial-and-error diagnostics but lacks the systematic diagnostic tools or expert guidance to pinpoint the root cause, especially for a complex fuel injection system.

Implied Software Gaps

A guided diagnostic tool that replaces manual trial-and-error part replacement and provides sensor-specific failure analysis.

App Concept

DiagnoseMyRide

A step-by-step guided diagnostic app for classic car owners that uses symptoms, vehicle data, and sensor readings to narrow down root causes. It replaces trial-and-error part swapping with a logical decision tree and community expert support.

Key Features

Vehicle-specific diagnostic flowcharts (e.g., for L98 TPI systems)
Sensor data interpretation with normal vs abnormal ranges
Community forum and mechanic-on-demand chat
Parts replacement log and test history tracker

Target Users: DIY classic car owners and hobbyists who work on older fuel-injected vehicles (e.g., 1980s-1990s GM, Ford, etc.) and need systematic troubleshooting without expensive shop visits.

Revenue Model: Freemium with $9.99 single-vehicle diagnostic plan or $19.99/month for unlimited vehicles and expert chat.
