Why does my car start then immediately stall?

If your car starts but then stalls quickly, several systems could be at fault: fuel delivery, ignition, or air intake. Common causes include a clogged throttle body (part of the air intake system), carbon buildup, or electrical issues. Here’s what to check: 1. Battery health – test by honking the horn; weak sound suggests low charge. 2. Incorrect air-fuel mixture – often caused by faulty sensors or engine control unit (ECU) miscalculations. 3. Unstable ignition voltage – linked to dirty fuel injectors or a faulty carbon canister solenoid valve. 4. Fuel injector leaks – these cause overly rich mixtures, making warm starts difficult. 5. Engine carbon deposits – these absorb fuel, leading to lean mixtures and hard starts, especially when cold. For persistent stalling, diagnostics by a qualified mechanic are advised.
