If a car loses power during acceleration, one of two things is causing the problem: not enough fuel or not enough power. Unfortunately, finding out an exact cause of power or fuel restriction is difficult.Know More
To figure out what the car is lacking, owners should press the accelerator when the car starts to lose power. If this helps the car gain power, the problem is not fuel delivery. If pushing the accelerator does not help the car run smoother, fuel restriction is the problem. To find the problem, owners should first check the fuel filter for clogs or impurities. After the fuel filter is clean, the owner should purchase a fuel additive designed to clear out blockages in the fuel lines. Also, it is important to check to see if there are any fuel lines that are leaking or cracked and to inspect the fuel pump to see if it is working correctly.
A loss of power can be caused by any number of problems. A good place to start is the exhaust system. Car owners should check for any holes or gaps between the exhaust and the muffler. If the car has a catalytic converter, this part also needs to be tested. This can be accomplished by hitting the converter with a rubber mallet. If there is a rattling noise, it needs to be replaced. Other possible causes of a loss of power include bad spark plugs and misfiring cylinders.Learn more about Car Parts & Maintenance
A broken car axle can cause the vehicle to sputter, make a clunking noise or create excessive vibration during acceleration. If the broken axle is not repaired it eventually prevents the car from moving.Full Answer >
The most common signs that a transmission is slipping include the revolutions-per-minute gauge being above 3,500, the car taking too long to coast or a delay in acceleration. Common causes of a transmission slip range from poor cleanup to defective parts.Full Answer >
Restricted fuel delivery and malfunctioning spark plugs are the most common reasons for cars to hesitate during acceleration. The first step to identifying the cause of this is to find out if the car is fuel-injected or if it has a carburetor. Fuel-injected cars and cars with carburetors deliver fuel differently, so there are different ways to diagnose and fix problems with acceleration.Full Answer >
The first step in troubleshooting a car problem is to identify the primary issue and when it happens, such as stumbling upon acceleration, and then take it through a question tree. Diagnostic sites, such as AutoZone.com or AutoMD.com, provide free question trees for car problems.Full Answer >
