Correlation does not imply causation. Could be just coincidence. I wouldn't be too hasty in deeming the cause bad gasoline. BTW does your car require 91 octane? I put premium on mine but its a required for my vehicle. I won't put anything less than 93 in it. Its tuned to exactly 11.0 A/F ratio and I'm running around 20 pounds of boost so I wouldn't risk it.
