Said It Here

Why does my car keep running after I turn it off?

When making multiple short stops back-to-back, the engine continues to turn, shake, or stall out instead of shutting down cleanly. This leaves the vehicle unable to start again a few minutes later, often requiring a jump start.

“Whenever i go to multiple places and turn it off and on consecutively (laundromat off/on, gas station off/on then home) itll still turn like its running then shake off and it feels likes its stalling out.”source ↗

“ONCE it even revved HIGHER for a few seconds before shaking off.”source ↗

“No, sometimes it will start on its own without a jump. Just the back to back starts. It wont start on the second try.”source ↗
