What
will happen if your catalytic converter is going bad?
Correct Answer
C. Your engine will turn off or stall upon a complete stop.
Explanation
If your catalytic converter is going bad, it can cause a restriction in the exhaust system, leading to a decrease in engine performance. This can result in the engine stalling or turning off completely when the vehicle comes to a complete stop. The catalytic converter plays a crucial role in reducing harmful emissions, so when it fails, it can disrupt the engine's normal operation and cause issues like stalling.

What will happen if your constant velocity or cv joint is going bad?
Correct Answer
D. Your wheels will make a clicking sound upon turning the wheels.
Explanation
If your constant velocity (CV) joint is going bad, your wheels will make a clicking sound upon turning them. The CV joint is responsible for transferring power from the transmission to the wheels, allowing them to turn at different angles. When the CV joint starts to fail, it can cause a clicking or popping sound, especially when making sharp turns. This is usually due to worn or damaged bearings inside the joint, which can lead to further issues if not addressed.

What will happen if you place the spark plug wires out of original order?
Correct Answer
E. Your engine will misfire upon starting.
Explanation
If you place the spark plug wires out of their original order, it will cause your engine to misfire upon starting. The spark plug wires are responsible for delivering the electrical current from the ignition coil to the spark plugs in the correct firing order. When the wires are placed incorrectly, the spark plugs will fire at the wrong time, causing the engine to misfire. This can result in rough idling, a decrease in engine performance, and potentially damage to the engine if left unresolved.
4.
What will happen if you do not screw your spark plugs in tightly or
correctly?
Correct Answer
A. The plug will blow out with a pop and the engine will turn off immediately after starting.
Explanation
If the spark plugs are not screwed in tightly or correctly, there is a risk of them blowing out with a pop. This can cause the engine to turn off immediately after starting.
5.
What will happen if your wheel barrings need tightened?
Correct Answer
B. Your vehicle will not ride smooth upon driving.
Explanation
If your wheel bearings need to be tightened, it means that they are loose. This can cause the wheels to wobble or shake while driving, resulting in an uncomfortable and rough ride. The loose wheel bearings can also lead to uneven tire wear and potentially cause damage to other parts of the vehicle's suspension system. Therefore, the correct answer is that your vehicle will not ride smooth upon driving.

What do you do and in what order if your brakes go out while driving an
automatic?
Correct Answer
C. Second gear then first gear then emergency brake.
Explanation
If the brakes go out while driving an automatic, the correct order of actions to take is to first shift into second gear to slow down the vehicle, then shift into first gear to further reduce speed, and finally engage the emergency brake to bring the vehicle to a complete stop. Shifting into second gear allows the engine to provide some resistance and slow down the vehicle, while shifting into first gear provides even more resistance. Engaging the emergency brake is the final step to ensure the vehicle comes to a stop safely.

What are parts of a distributor?
Correct Answer
D. Cap and rotor and camshaft.
Explanation
The correct answer is "Cap and rotor and camshaft." In a distributor, the cap is responsible for distributing the high voltage electricity from the ignition coil to the correct spark plug. The rotor rotates inside the cap and makes contact with the terminals, sending the electricity to the spark plugs in the correct firing order. The camshaft, on the other hand, is responsible for opening and closing the distributor's mechanical points, which control the timing of the spark. Therefore, the cap, rotor, and camshaft are all essential parts of a distributor.
