Context: Engine was warm at the start of logging. The car was left idling for the first ~2 minutes, followed by normal driving—vehicle performance was smooth during this period. A few hard throttle pulls were performed, and the car was taken onto the parkway (vehicle speeds began to exceed 40 mph). During a subsequent attempt to accelerate, the engine began to strain. Shortly afterward, the "trifecta" warning lights appeared, the vehicle started to decelerate, and RPMs began bouncing between 1500–1800 RPM.
