Why does a car run when it’s cold?

While cold, the ring-cylinder mate is tight, keeping the combustion gasses from blowing by and allowing the engine to run.

What causes a car to stall on a cold start?

It also manages the idle under changing engine loads, like when you kick on the air conditioning, turn on the headlights, or turn up the radio. When the idle air control valve malfunctions, you may experience a rough idle or the vehicle may stall entirely. This is especially true on cold starts.

Why does my car stall at highway speeds?

The engine may start and idle fine, but run out of power or even stall at highway speeds. If the engine starts right back up after stalling, the likely cause is low fuel volume delivery because of a weak pump. If the engine is running normally one minute, but suddenly quits, loss of ignition may be the problem.

When does a shorted sensor cause an engine to stall?

A shorted sensor doesn’t always set a check engine light or MIL (malfunction indicator light).
