6 Causes Of Car Won’t Accelerate Symptoms

4. Dirty or Clogged Fuel Filters

A dirty or clogged fuel filter is another reason for the appearance of the symptoms of car not accelerating when required to do so. With a dirty fuel filter, the engine won’t be getting enough fuel which means that the vehicle won’t be going anywhere nor will it be giving the acceleration performance that it should. Replace it as soon as possible.

5. Clogged or Dirty Air Filters

Just like the fuel filter provides the engine with the clean fuel, the air filters provide the engine of a vehicle with clean to be used in the air-fuel mixture which will be sent to the combustion chambers to burn. If an air filter is clogged, then the engine won’t get the right air-fuel mixture resulting in decrepit and slow acceleration. Replace it as soon as possible.

6. The Timing Belt

This component is as it sounds. The timing belt is something like a VIP in the list key of components of an engine. If this belt is off even by 1 tooth, it may cause some pretty notable acceleration problems.

However the list of culprits does not end here. The culprits behind the slow acceleration may be a slipping clutch, the transmission system itself or an unexpected or unrelated problem which may surprise even the veterans in the mechanics.

Take the vehicle to a reliable mechanic and let him give it a full checkup. This will let that mechanic catch onto that problem and will let him deal with it.

  1. I have a 98 ford ranger that occasionally looses power & won’t accelerate. Can happen anytime on freeway or surface streets. It only last a few seconds then it’s ok again. No smells, no warning lights, nothing to indicate a problem. Mechanics can’t find any problem. Replaced battery then fuel filter then idle control motor. Still same problem but only for seconds & can go 200 to 1000 miles before it happens again. Can’t keep fix in stuff it isn’t. Any suggestions?

    1. it so complicated, so the problem comes sometimes and take only for a second?
      i mean when problem occur, it continuous or just a second then comeback normal again?

    1. Possible causes and easiest step you can do:
      check clogged exhaust pipe
      check fuel pump weak
      and please also chcek the compression of each cylinder

  2. i have a 99 honda crv. the timing belt jumped which affected the four valves out the sixteen valve, my mechanic worked on the engine by replacing the valves and the gasket but since after the work the car acceleration is not normal again. it is so slow especially at idle speed.when you accelerate it somehow sluggish to pick. what could be the likely problem

  3. I have a 2005 Toyota Camry drives normal for a while then just stops, motor is still running but when you push on the gas pedal it does nothing. I can shut the car off and restart it and I will drive fine again for a while.

  4. I have a similar problem, my car is Honda EOD 2003 V6. It won’t accelerate at all or even pick up eventually. Its just dragging and sucking my fuel like no man’s business. Please i need urgent help.

    1. check engine light, if no engine light possible causes
      fuel pump weak
      clogged exhaust pipe
      or even loss compression
      please check the easiest way first

  5. I have a 97 Acura 3.0 CL, it’s making clicking noises on the passenger side by the dashboard. It starts, will drive, but at a certain distance it won’t let me accelerate when I press the gas. I can turn it off and wait a few and it would start back up and drive again. What might that be?
