had a check engine light for o2 sensor bank 1 sensor 2 POST CAT. car would act weird, sudden “boost” of power randomly, not responded correctly with throttle. cleared check engine light this morning, car sat after the code was cleared for two hours, then after two hours after clearing did 2, 3rd gear hw pulls. check engine light did NOT come back on. initially, cel was on for an exhaust leak, leak has since been fixed for a week now before these logs.
