Diagnostic Flowcharts
Rough Idle and Stall Flowchart
A practical rough-idle workflow for intake leaks, fueling, ignition quality, idle control, sensor plausibility and mechanical condition.
Open Protected ChecklistsWorkshop Purpose
This resource turns a broad topic into a repeatable workshop reference. It is designed for students and mechanics who need a clear diagnostic or study path before downloading forms or using the live calculators.
How To Use It
Start with the focus points below, gather measurements, then move into the related checklist or calculator. The goal is to document the failed test instead of guessing the failed part.
Focus Points
- Vacuum leaks
- Idle actuator or throttle body
- Fuel pressure and injector behavior
- Compression and valve clearance
Related Next Step
Use the protected checklist library for printable worksheets, or return to the live calculator hub when the next decision needs a number: voltage drop, compression, sag, gearing, brake torque, charging time or fuel range.
