Frequently Asked Questions (FAQs)

1. How do you adjust idle speed on fuel injected?

Adjusting the idle speed on a fuel-injected vehicle can vary depending on the make and model. Some motorcycles may have a knob near the engine compartment that can be turned clockwise or counterclockwise to adjust the idle speed. However, it is important to consult the vehicle's manual or seek professional assistance for specific instructions on adjusting the idle speed.

2. How does the idle speed control valve work?

The idle speed control valve, also known as the idle air control valve, plays a crucial role in maintaining a smooth idle for the engine. It allows air to bypass a closed throttle plate when the engine is at idle, preventing stalling and ensuring a consistent idle speed. This valve is controlled by the vehicle's computer system and responds to various sensor inputs.

3. Can you adjust the idle on a fuel injected car?

In most fuel-injected cars, the idle speed is controlled by the vehicle's powertrain control module (PCM). The PCM uses complex computations and sensor inputs to determine and adjust the idle speed. Unlike a carburetor, the idle speed on a fuel-injected car is not adjustable manually.

4. What causes the idle speed control to be high?

Several factors can contribute to a high idle speed. Common causes include a dirty air intake or a cracked air intake tube, which can disrupt the airflow and lead to an increased idle speed. Additionally, a malfunctioning powertrain control computer can misinterpret information and result in a high idle speed.

5. What happens if idle air control valve goes bad?

When the idle air control valve fails, it can disrupt the airflow to the engine, leading to engine stalling. The severity of this symptom can vary, ranging from occasional stalling to immediate stalling after ignition. If you suspect a faulty idle air control valve, it is recommended to have it inspected and replaced if necessary by a qualified mechanic.
