My car won't start. What could be the problem?
There are various reasons that could be causing this problem. In finding out what's causing your engine not to start, start with the battery. If the battery has run out of charge, it will not be able to generate the voltage needed to start your car. You also need to check if your battery is still working. If it is already dead, you should replace it with a new one. To find out if a bad battery is causing the problem, try to jumpstart your car. If your engine roars to life, then it is the battery. However, if the battery is fine, you need to move on to the starter circuit. Check if the battery cables are still properly connected and that the battery ports are clean so the power can flow freely from the battery. A faulty ignition switch, or a faulty starter relay or solenoid can be the one causing the problem. Your car's fuel system should also be checked, as faulty fuel system components can affect your car's ignition.
I can feel my engine hesitating and jerking when I accelerate. What's causing this and how do I fix it?
This can be a sign of a problematic mass airflow sensor. The mass airflow (MAF) sensor determines the amount of air that is flowing into the engine. The information gathered by the MAF sensor is then used by the engine control unit to determine how much fuel should be delivered to the engine. If the mass airflow sensor fails, it will give a faulty reading that will affect the fuel and air mixture. If the fuel and air mixture is compromised, it will not be properly burned, thereby causing the engine to hesitate. The jerk you feel is the fuel and air mixture exploding inside the combustion engine. To fix this problem, you need to replace the faulty MAF sensor with a new one.
My car nose dives and swerves when I step on the brakes and when I slow down. Is it a busted shock?
If the hood of your car dips or if your car swerves when you step on the brakes or when you are slowing down, you might be having worn out or busted shocks. Other symptoms of worn shocks are if you are having trouble stopping, if your steering wheel is vibrating when you are driving, if your car slides to the side, and if your tires keep wearing out unevenly. If you are experiencing any or a combination of these, you should have your shocks checked right away. When a shock absorber goes bad, there is no way it can be fixed and the option you have is to replace the busted one with a new one.
Shock absorbers are made to last for up to five years. However, how you drive, where you drive, and the loads your car carries will affect the service life of the shocks. If you practice good driving habits, you can expect your shock absorbers to have a maximum service life.
