Miss fires at 60 to 75 miles per hour

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. Your concern is difficult to understand, because if a misfire – – if that's what it is – – is occurring so randomly, and rarely, it will be difficult to troubleshoot. Diagnostic trouble codes indicating problems that may have been noted in the engine's processor may be present. These could be important clues to interpret while trying to figure out what is happening when the malfunctions occur.
