Truck Makes Tickling Noise When Accelerating – How To Fix

The best thing about driving a truck is hearing the roaring sound of the engine. But sometimes, the roaring sound can be accompanied by tickling noise, which should not be the case. The tickling sound whenever you press the gas pedal indicates that one of the components is faulty. This guide will cover all the potential problems, and how to fix them.

Law Oil Pressure

Law oil pressure harms the engine as the metallic parts hit and rub against each other. The tickling sound results from the dry engine parts rubbing and hitting against each other. In such a situation, you will hear the tickling sound when your truck is stationary but the engine is running. However, the sound intensifies when you press the gas pedal. 

How to Fix Tickling Noise When Accelerating

First, you need to refill the oil reservoir, but if you did this recently, check for leaks, as this can deplete oil from your truck quickly.

Always change the oil filter anytime you change your oil. Low oil pressure results from a clogged oil filter, leading to an inadequate oil supply to the engine. 

Exhaust Leaks

The exhaust system does the role of expelling the combustion by-products from the combustion chamber in an organized and controlled manner. 

Exhaust leaks can happen anywhere within the exhaust system. But the leak within the exhaust manifold will manifest as a tickling sound within the engine compartment.

How To Fix Tickling Noise Caused By Exhaust

Exhaust manifold leaks sound serious, but fixing them is a simple procedure. Your mechanic can patch the leak. If the exhaust manifold is faulty, you will replace it at a cost though not expensive.

Faulty Valvetrain

The engine has various valves. All these valves are in two categories that are intake and exhaust valves. The valvetrain does the role of controlling the intake and exhaust valves. If the valvetrain or the valves are faulty, you will hear a tickling sound when you press the gas pedal. When this happens, your engine will misfire, reducing performance. 

How To Fix

It is easy to adjust the valvetrain. If you have the necessary tools, you can work on it as a DIY project. But you can consult your mechanic to do it on your behalf, which will cost $80 to $150.

Faulty Spark Plugs

The spark plugs seal every cylinder from the top. If not well fitted or cracked, the exhaust gases will bypass the seal, resulting in the tickling noise. Sometimes, the sparkplugs can damage the cylinder head threads, and you must replace them. 

How To Fix Tickling Noise From Faulty Spark Plugs

If your spark plugs are faulty, consider replacing them, but if they are loosely fitted, consider tightening them.

If the spark plug has damaged the cylinder head, consider replacing or repairing it, which is expensive.


Several issues cause a tickling noise whenever you press the gas pedal. It is essential to discover the possible cause of the tickling sound as it poses a greater risk to your engine. A damaged engine right from the cylinder head is expensive to fix. The above are the possible causes of tickling sounds and how to fix each.
