Problem overview

Some Chevrolet Monte Carlo owners report experiencing sputtering issues that may be linked to problems with the spark plugs or the mass air flow sensor. These sputtering symptoms can arise from various factors, including complications within the fuel system, faulty ignition coils, or issues with the ignition system itself. Additionally, a malfunctioning mass air flow (MAF) sensor can disrupt the measurement of air entering the engine, contributing to sputtering. Owners have noted that inefficient combustion, often due to bad spark plugs, can lead to sputtering during acceleration or when the vehicle is at a standstill. It is recommended that affected owners have their spark plugs, ignition system, and mass air flow sensor thoroughly inspected to determine and resolve the underlying issues.
