1997 Volvo 960 Cylinder #3 Misfire: Coil Pack Failure Diagnosis and Solutions

Model: 1997 Volvo 960 Fault Code: P0300 Posted: 2009-05-12 04:39

Hi community, I've been experiencing a persistent cylinder #3 misfire on my 1997 Volvo 960. Despite replacing the coil pack with a new one just last week, the issue continues to appear in the diagnostic trouble codes. I'm looking for insights into why cylinder #3 specifically might be failing—could it be related to ignition timing, spark plug condition, or another component? Any real-world experiences or troubleshooting steps for this model would be greatly appreciated.
