What could lead to an engine stalling?

An engine stalling can occur when there is insufficient fuel delivery. This is primarily because an engine needs a specific air-fuel mixture to operate smoothly. When the fuel delivery is inadequate, the engine may not receive enough fuel to maintain its operational requirements, leading to a loss of power and ultimately causing the engine to stall. Factors that can cause insufficient fuel delivery include a clogged fuel filter, failing fuel pump, or defective fuel injectors, all of which prevent the engine from receiving the proper amount of fuel.

Other options, while they may negatively impact engine performance, do not directly lead to stalling in the same way that fuel delivery does. For example, excessive oil pressure can actually indicate a healthy oil circulation and lubrication system, while improper tire pressure relates to vehicle handling rather than engine function. High temperature levels can indicate overheating but may not immediately translate to stalling unless it affects components in a way that halts engine operation. In summary, insufficient fuel delivery is the primary cause directly linked to engine stalling.
