How long does it take a car to reach normal operating temperature?
Instead, there are typically markings for cold and hot on the edges of the gauge and a normal range in the middle. In most cars, the temperature needle will be at or near the center when the engine is at normal operating temperature, which usually takes at least a minute or two to reach after starting a cold engine.
What causes rough idle on cold start?
An engine that is doing a rough idle when cold can also be the result of faulty spark plugs or damaged spark plug wires. Spark plugs use the electrical current produced from the ignition coils to ignite the correct ratio of the air to fuel mixture within the combustion chamber in the engine.
