It can be a frustrating experience if your car won’t respond when there is a need for speed. There are many culprits why your car won’t accelerate as it ought to, it could be as a result of a mere stuck emergency brake (hand break) to a complex electrical fault. When you encounter such issue, you can attempt a DIY technique by changing the spark plugs if it has served well enough – you can order for a genuine spark plugs here – or make sure your see your technician as soon as you can if the problem persists.
The following address only few of the common causes of a sluggish car movement:
EMERGENCY BREAK IS ON OR STUCK
This is actually one of the most common reasons that a car will not move or seems to be experiencing poor acceleration. The brake may be on simply because the driver forgot to disengage it, or it may be stuck.An emergency brake can become stuck if it is left on for a long period of time or if it was applied with more force than usual.
BAD SPARK PLUGS
If your vehicle is accelerating poorly it is fairly easy to tell. It feels as if the vehicle doesn’t want to respond when you put your foot down, or it does but not instantly as you’ve become accustomed to. It can also feel as if your vehicle is trying really hard to pull itself along. This sluggishness can be easily fixed by having the vehicle serviced with a spark plug change.
AN IN-EFFICIENT FUEL SUPPLY SYSTEM
A mal-function of any of the components that make up the fuel system won’t allow enough fuel get to the combustion chamber when there is demand for speed. For example, if the fuel filter is dirty it will prevent enough fuel needed for acceleration from reaching the engine. You can either clean your filter or replace it to fix the problem. A clogged supply lines, a bad fuel pump, a faulty fuel nozzle can also hold your car down.
MALFUNCTIONING ELECTRONIC THROTTLE CONTROL
Most late-model vehicles utilize an electronically controlled throttle to control airflow into the engine. This system relies on multiple electronic inputs, computers, and motors to control engine speed. If the system detects a malfunction, the computer will usually shut down the throttle opening as a precaution. In this case, multiple error codes will be logged, a Check Engine light may be displayed, and the vehicle may not exceed 35 to 40 mph.
