How do you fix a sluggish acceleration?
If your car is not accelerating properly, check the air filter. The air filter traps dirt, debris and other impurities to keep them from entering the combustion chamber. A clogged air filter starves an engine of much-needed air, skewing the air/fuel mixture that affects acceleration.
What does a vacuum leak sound like when accelerating?
Hissing Sound This is a common symptom of a vacuum leak in a car. If caused by a vacuum leak, the hissing sound should come from the engine area when the engine is running. Broken vacuum hoses create this high pitch sound as they suck air through the leak. If you follow the hissing sound, it will lead you to the leak.
Why did my car stop accelerating while driving?
