The P0302 code in your 2022 Chevrolet Camaro indicates that cylinder 2 is misfiring. The 2022 model year continues with the proven engine lineup: 2.0L turbocharged four-cylinder (LTG), 3.6L V6 (LGX), 6.2L LT1 V8, and the supercharged 6.2L LT4 V8 in the ZL1. Each engine presents unique diagnostic considerations for cylinder 2 misfire resolution.
Identifying Your Engine
Engine identification is essential before diagnosis. The base 1LS and 1LT trims typically have the 2.0L turbo. The LT1 trim uses the 3.6L V6. SS models feature the LT1 V8, while ZL1 models use the supercharged LT4. Cylinder 2 location and diagnostic approach varies by engine.
Turbo Four-Cylinder Issues
The 2.0L LTG turbo engine can experience misfires from ignition coil failure, spark plug degradation, direct injection carbon buildup, and boost system problems. Wastegate sticking can cause inconsistent boost affecting specific cylinders. The four-cylinder shows pronounced misfire symptoms.
V6 and V8 Considerations
The 3.6L V6 shares common direct-injection concerns including carbon buildup and ignition system wear. The LT1 and LT4 V8 engines are robust but can experience coil or plug failure, especially with track use. The supercharged LT4 adds boost system variables to diagnosis.
Performance Engine Diagnostics
High-performance engines require quality diagnostic equipment. Scan for all codes including transmission codes that might indicate related issues. Monitor misfire counts under various conditions including wide-open throttle. Compression and leak-down tests verify cylinder integrity.
Repair and Prevention
Use OEM-quality or performance-grade replacement parts. AC Delco or equivalent iridium spark plugs maintain proper heat range. Replace ignition coils with quality units. Direct injection engines benefit from periodic intake cleaning. Always use premium fuel as specified for performance engines.
