1997 Chevrolet 4.3L Engine Misfire with P0302 Code - Diagnosis and Solutions

Model: 1997 Chevy 4.3L Fault Code: P0302 Posted: 2018-01-01 16:42

I own a 1997 Chevrolet truck equipped with a 4.3L V6 engine. When I first purchased it, the vehicle exhibited a misfire issue, which I initially assumed was normal. However, the problem has persisted despite replacing the distributor, ignition wires, and spark plugs. After clearing the P0302 diagnostic trouble code (DTC), the code returns repeatedly. I've tried multiple repairs but still see the same error. What should I do next to resolve this issue? Any insights into potential causes or further troubleshooting steps would be greatly appreciated.
