Chevrolet Equinox engine cuts off when stopping and jerks, multiple components replaced on Chevrolet Equinox

Some Chevrolet Equinox owners report experiencing engine stalling and jerking when stopping, which may stem from several underlying issues. These owners have identified a faulty ignition system, including malfunctioning spark plugs or ignition coils, as a potential cause that prevents the engine from receiving the necessary spark for combustion. Additionally, problems with the fuel system, such as contaminated fuel, have been reported to lead to immediate stalling. Another concern is the idle air control (IAC) valve, where a faulty unit can cause the engine to idle too low, resulting in stalling at idle. Some owners also experience engine misfires, often linked to spark plug or coil pack issues, which can cause jerking during acceleration. If these problems persist even after replacing multiple components, it is recommended that owners seek a comprehensive diagnostic check from a qualified mechanic to identify any other potential issues contributing to the engine's performance problems.
