P0316 - Misfire Detected on Startup (First 1000 Revolutions)

A misfire was detected during startup.

Treat the code as the starting point: compare symptoms, likely causes, and repair paths before pricing parts or moving into an estimate.

Code Overview

A misfire was detected during startup.

Common Causes

• Worn plugs or coils
• Fuel delivery issue
• Leaking injector
• Low compression on startup

Diagnostic Steps

1. Note if the misfire clears once warm
2. Check for coolant or fuel fouling on plugs
3. Scan for cylinder-specific misfire companions

Likely Repairs & Cost Guides

Use symptoms, scan data, and quick checks to confirm the likely repair path before pricing parts. The estimator helps compare repair paths before replacing anything unnecessarily.

Related OBD Codes

Browse nearby code-family pages when the same fault pattern overlaps across systems, such as misfire, lean fuel trim, EVAP sealing, cooling, or charging faults.

Next Steps

Move from code lookup to diagnosis, then estimate the likely repair only after symptoms, causes, and checks point to the same path.
