Buick Verano intermittent stalling while driving slowly with AC on on Buick Verano

Some Buick Verano owners report experiencing intermittent stalling while driving slowly with the AC on, which may be attributed to several factors. Common causes include issues with the fuel system and the need for sensor replacements. Additionally, some owners have been advised by mechanics that a sensor problem could be contributing to the stalling. In certain cases, a faulty ICM ground wire has been identified as a potential cause of stalls in Buick vehicles. Furthermore, problems with the variable valve timing may lead to engine stalling at low RPMs when the AC is engaged. To effectively address these concerns, it is recommended that owners have their fuel system, sensors, ICM ground wire, and variable valve timing system inspected by a qualified mechanic.
