2011 Mini Cooper S; ~90,000kms
This recurring issue is giving me a headache. For the past year, on occasion when I have been driving down the highway, I have been halted by a half-red check engine light and reduced power. Naturally, I immediately proceed to the nearest location to pull over and shut the engine off. After the car rests for an hour or so, I turn the ignition on and the engine light is gone and full power is restored. The OBD2 error log indicates cylinder misfire in multiple cylinders, which in my mind indicates a possible ignition or fuel delivery issue. Hoping that a cheaper option would fix the issue, I replaced the coils and sparkplugs then cleared the codes. Then one month later, the same issue happened again. This time I had the car inspected by a mini dealership. Their solution was to replace the fuel injectors. A month after that was done the issue happened again, leaving me scratching my head. Does anyone have any idea of what is happening here? Any suggestions of what I can do next without breaking bank again?
