Chevrolet Spark jerking during acceleration with RPM revving issue after new transmission installation on Chevrolet Spark

Some Chevrolet Spark owners report experiencing jerking during acceleration, often linked to misfires caused by worn or fouled spark plugs or coil packs. Additionally, they may notice RPMs unexpectedly jumping from 2000 to 3000 while accelerating, indicating potential ignition system issues. Some owners also report intermittent hesitation at lower speeds, which can persist even after a new transmission installation, suggesting possible underlying engine problems. Furthermore, consistent jerking during both acceleration and deceleration is a concern that could signal serious issues with the engine or transmission, risking further damage and increased repair costs if left unaddressed. It is recommended that owners have their vehicles thoroughly inspected by a qualified mechanic to diagnose and resolve these issues promptly.
