The P0303 diagnostic trouble code on your 2024 Acura Integra indicates the powertrain control module has detected consistent misfires in cylinder 3. The 2024 Integra offers two turbocharged four-cylinder options.
2024 Integra Engine Options
The 2024 Integra features the 1.5L turbo four-cylinder (200 hp) or the Type S's 2.0L turbo (320 hp). Both are inline-4 engines with cylinder 3 positioned third from the front.
Typical Causes
- Ignition Coil Problems: Turbo applications stress ignition systems
- Spark Plug Condition: Both engines require turbo-spec plugs
- Boost System Integrity: Leaks cause lean misfires
- Fuel Injector Issues: Direct injection deposits or failures
- Carbon Deposits: GDI engines accumulate valve carbon
Diagnostic Process
Identify your engine type first (Type S uses 2.0L). Use Acura diagnostics for turbo-specific data. Monitor boost pressure and misfire counts. Test ignition components systematically.
Repair Recommendations
Replace faulty ignition coils with OEM-spec components. Install properly specified spark plugs. Repair boost leaks identified during testing. Professional carbon cleaning addresses valve deposits.
