Honda CR-V P0301 Misfire: Is Bad Gas Really the Cause? | Single Cylinder Issue After 3 Months
Our Honda CR-V has experienced three instances of power loss over the past three months, each time accompanied by a P0301 diagnostic code indicating a misfire in cylinder 1. Despite refueling weekly during this period, our dealer has suggested that 'bad gas' is responsible for the issue. Given that only one cylinder is affected and the problem has persisted over such a long timeframe, we're questioning whether poor fuel quality could truly be the root cause. Cleaning the gas tank reportedly costs over $500 — is this realistic or plausible? We're seeking expert insight on whether bad gas can specifically impact just one cylinder after months of regular refueling.
Something doesn't add up. If only cylinder 1 is misfiring, it's highly unlikely that the issue stems from poor fuel quality. A single-cylinder problem over an extended period is unusual for bad gas — especially when fuel has been changed regularly. Consider getting a second opinion and verify whether this is being handled by an authorized Honda dealership.
