Why does my car stall when I come to a stop?
Vehicles sometimes shut off or shake and drop RPMs when coming to a stop sign, red light, or while reversing early in a drive. This happens even with accessories like the AC and radio turned off, leaving drivers uncertain about mechanical issues while a persistent P0328 code returns.
