Persistent cylinder 3 misfire in 2014 Ram 1500 that two mechanic shops could not diagnose or fix after extensive testing and service.

Standard diagnostic tools and procedures failed to identify the root cause (likely carbon buildup on valves or pistons), leaving the owner with no clear resolution despite two shop visits.

Implied Software Gaps

Diagnostic tool that specifically identifies carbon buildup on valves and pistons as the root cause of misfires

App Concept

CarbonCut Diagnostics

A specialized automotive diagnostic tool that pinpoints carbon buildup in combustion chambers and intake valves using a combination of borescope imaging and pressure wave analysis. It provides a clear go/no-go for carbon cleaning and recommends the most effective cleaning method (chemical, media blasting, or manual).

Key Features

Automated borescope image recognition to quantify carbon deposits
Pressure wave analysis to detect misfire patterns caused by carbon
Cleaning method recommendation engine based on deposit severity
Fleet reporting and VIN-specific service history integration

Target Users: Automotive repair shop owners and technicians diagnosing persistent misfires in modern direct-injection engines

Revenue Model: One-time hardware sale ($499) + annual software subscription ($199/year for updates and cloud analytics)
