Chevrolet Avalanche 1500 jerking on acceleration and occasional shutdown on Chevrolet Avalanche 1500

Some Chevrolet Avalanche 1500 owners report experiencing jerking during acceleration and occasional shutdowns, which may be linked to several issues. Many have noted that if the check engine light is illuminated, running a diagnostics test can help identify the underlying problem. Fuel system issues, such as clogged fuel lines, can restrict fuel flow and cause jerking, particularly at constant speeds due to dirt or debris buildup. Additionally, signs like rough idling and poor fuel economy may indicate that throttle body cleaning is necessary to remove accumulated contaminants. Some owners have also encountered issues related to deceleration calibrations, where improper fuel injection during deceleration leads to jerking and bucking. Furthermore, hesitation or surging during acceleration may prompt owners to inspect the serpentine belt and associated components for wear. Addressing these potential causes through thorough diagnostics and maintenance can help resolve these concerning performance issues.
