GMC Envoy stalling issue at low speeds possibly related to sensor after solenoid and spark plug replacement on GMC Envoy

Some GMC Envoy owners report experiencing stalling issues at low speeds, particularly after replacing the solenoid and spark plugs. These problems may be linked to a faulty or incorrectly calibrated throttle position sensor (TPS), which is crucial for monitoring engine performance. Additionally, issues with the variable valve timing control solenoid can negatively impact valve timing and contribute to stalling. Some owners also find that a malfunctioning camshaft sensor, especially if not properly installed after replacement, leads to similar stalling concerns. Problems with the idle control system, including the idle air control valve or throttle body, can further exacerbate these issues, making cleaning and maintenance essential. Furthermore, if the check engine light is illuminated, retrieving trouble codes from the PCM can provide valuable insights into the underlying causes of stalling. It is recommended that owners thoroughly inspect and potentially recalibrate or replace these components to effectively resolve the stalling problem.
