Why would car stall when driving?

Fuel System Issues

* Clogged fuel filter: A clogged fuel filter can restrict the flow of fuel to the engine, causing it to stall.

* Faulty fuel pump: A faulty fuel pump can't deliver enough fuel to the engine, which can also cause stalling.

* Fuel injector problems: Dirty or faulty fuel injectors can also cause stalling by disrupting the fuel flow.

Ignition System Issues

* Faulty spark plugs: Worn-out or damaged spark plugs can prevent the engine from firing properly, causing it to stall.

* Bad ignition coil: A bad ignition coil can't produce enough spark to ignite the fuel, which can also lead to stalling.

* Distributor problems: Distributor problems (on older vehicles) can also cause stalling by disrupting the ignition timing.

Electrical System Issues

* Weak battery: A weak battery can't provide enough power to start the engine or keep it running, which can cause stalling.

* Alternator problems: A faulty alternator can't charge the battery, which can eventually lead to stalling.

* Starter problems: A faulty starter motor can't crank the engine, which can also cause stalling.

Other Possible Causes

* Air intake problems: A blocked or restricted air intake can prevent the engine from getting enough air, which can cause stalling.

* Exhaust system problems: A clogged or restricted exhaust system can back up exhaust gases, which can also cause stalling.

* Computer problems: A problem with the engine computer (ECU) can disrupt the engine's operation, which can also cause stalling.
