I was driving today and I popped code 43 like 3 times when I got on the gas, I was wondering if using too much octane booster would cause it to go off, I never felt or heard a misfire just a code for no reason, my dad poured a thing of 108 octane boost in since I. Let it sit for 3 weeks when I went up north to see my wife, but he also put 91 octane in after that and I've never had a problem with code 43 before any info on this guys?
