For a combustion engine (gas or diesel) to operate well, the fuel and air must be precisely balanced. If there is any deviation from this combination, the engine may run too lean (not enough air) or too rich (not enough fuel). A fuel/air mixture that is excessively lean is most likely the cause of an engine’s hesitation when accelerating. When an engine is operating inefficiently, it will start to exhibit symptoms like hesitancy, which will only become worse over time. Have your vehicle checked out right away if you detect any signs, such as hesitation.
To sum up
Most of the time, relatively simple issues like clogged filters, leaking hoses, and an engine running too lean due to a broken sensor are to blame when a Nissan Murano hesitates when you try to accelerate.
Slow acceleration is typically not the only symptom of other, more expensive problems.
Repairing whatever caused the issue will be worthwhile for a car that is in good condition.
It’s not just you who is experiencing this issue. In order for us to assist you in diagnosing it, you’ll need to be more precise. It’s either the throttle body, the ground under the dash, or a defective CVT at this point. Which party is at fault can be determined based on the failure characteristics.
Therefore, elaborate on what is occurring to your RPMs. You depress the gas pedal after coming to a complete halt. What do you notice about:
1) The RPMs remain modest. The MO will pause briefly before accelerating farther if you give it additional gas.
2) The MO remains stationary, while the RPMs follow the accelerator. The MO will eventually take flight.
If it’s number one, either your throttle body or the ground under your dash is bad.
Causes of Nissan Murano slow acceleration and solutions
Not only is it frustrating to drive your Nissan Murano with hesitation in the engine or slow acceleration, but it may also be risky when overtaking or crossing a street. Slow acceleration is a sign of a deeper issue with your Murano that has to be fixed right away to prevent further harm to your car.
The most frequent reasons for Nissan Murano’s poor acceleration include a filthy mass air flow sensor (MAF), a dirty air filter, a dirty fuel filter, a broken oxygen sensor, a dirty throttle body, worn spark plugs, and a dirty catalytic converter. Throttle position sensor (TPS) issues, defective ignition coils, filthy fuel injectors, clogged engine oil filters, transmission issues, worn piston rings, and blown head gaskets are less frequent reasons.
It’s a 2012 Murano that’s started to hesitate just a little.
Usually, a defective O2 sensor or possibly a bad mass air flow sensor is the problem. You actually need someone who can understand the inputs on a scan tool to figure out which is the problem without a check engine light. Additionally, inspect the air filter box and the ductwork that connects it to the throttle body. This can sometimes loosen or crack, generating a problem with the fuel mixture that can result in this kind of hesitancy.

Nissan Murano stutters when accelerating because of the accelerator cable
Another potential cause of reluctance during Nissan Murano acceleration, whether you are moving, stopped, in hot or cold weather, or accelerating, is a throttle cable that is severely worn. Verify the level of wear on your accelerator cable because if it is severely worn, it will not slide easily in its sheath and will eventually snap.
You can examine a number of items, including:
You mentioned that a DTC readout was completed without any errors, but typically one of the first things to do is perform an ECU code readout with a portable scan tool to determine if any fault codes are set.
- – Insert a temporary fuel pressure gauge into the fuel rail’s fuel feed pipe. Idle the engine after starting it. The figure for the fuel pressure should be close to 51 psi. If the value is too low, either the fuel pressure regulator or the fuel pump may be subpar.
- – The cam timing can be off. Check the chain guide to see whether it’s cracked or broken, as it can be both.
- – A significant intake system vacuum leak could exist. Make sure the intake manifold nuts are snug by checking them. Possible gasket failure. Additionally, look for cracks or loosened clamps in the intake plenum bellows at the throttle valve and the MAF.
– Install a temporary fuel pressure gauge between the fuel rail and the fuel supply pipe. Start the car and let the engine idle. 51 psi or thereabouts should be the reading for the fuel pressure. If the reading is very low, there may be a problem with the fuel pressure regulator or the gasoline pump.
– The cam timing might not be accurate. Check the chain guide to determine if it has broken or if it has cracked and some teeth have skipped.
– A significant vacuum leak in the intake system could exist. Verify the tightness of the intake manifold nuts. It’s possible the gasket failed. Additionally, check for cracks or loosened clamps in the bellows at the throttle valve and the MAF on the intake plenum.
What is the Nissan Murano’s most typical issue?
- The Murano Soft Brakes. The brake pedals on the 2009 Nissan Murano are soft and spongy, going all the way to the floor, which dangerously lengthens stopping distances.
- Visor Is Constantly Dropping.
- Sunroof explodes and rattles.
- OCS Warning as well as Airbag Issues.
- Gas spills and EVAP clogs
When did Nissan Murano transmission issues start?
Nissan Murano 2010 Problems A transmission issue has led to the recall of the 2010 Nissan Murano. In September 2017, the recall was announced, affecting around 8,000 automobiles. The Murano’s engine is noisy and underpowered.
Do Nissan Murano transmission issues have a reputation?
One of the primary problems with the Nissan Murano is its continuously variable transmission, which is typical for the company. Nissan automobiles with CVTs are more prone to trembling, shuddering, unexpected acceleration, and even gearbox failure.
How many miles can a Nissan Murano travel?
The quick answer to how long a Nissan Murano can last is as follows: The typical Nissan Murano has a lifespan of up to 200,000 kilometers. Your Murano should last approximately ten years if you drive it an average of 15,000 kilometers every year.
What is the Nissan Murano’s typical lifespan?
We determined that the Nissan Murano is more than capable of operating well well past the 100,000-mile mark based on our extensive investigation into the used car market.
There are still previous model years on the road today, according to anecdotal evidence from nations that acquired the Murano before its 2009 North American premiere.
Given that the Nissan Murano has an average lifespan of 200,000 miles and that the average annual mileage is 15,000 miles, you may anticipate at least 13 years of service from the vehicle.
Case-by-case reports of longevity can vary depending on a number of circumstances, much like with most autos. These include of routine upkeep, driving practices, intervals between fluid changes, and extensive off-road driving.
Consider driving cautiously and make sure to refer to your service manual to stay current on maintenance in order to get the most out of your Nissan Murano.
Why does my car jerk when the rpms are low?
My parents handed me down a 2012 Toyota Camry when I first learned to drive. Recently, the engine has been sluggish at slower speeds. I want to keep running this automobile as long as I can! What results in engine judder at low RPM?
In less than two minutes, find out if your auto insurance is being overcharged.
You know it’s not good when you press the gas pedal and nothing happens, even for a brief period of time.
There are numerous reasons why your engine could hesitate at low RPM, all of which lead to an improper ratio of fuel, air, compression, and spark. Let’s begin with the most straightforward reasons first:
- Bad fuel: Ensure that you are filling your automobile up with high octane fuel. Premium fuel will lessen knock, which occurs when the air/fuel mixture ignites prematurely and increases cylinder pressure.
- Bad vacuum hoses: Inspect your engine’s vacuum hoses for wear, cracks, or holes. Engine hesitancy occurs at low RPMs when there is any air leakage.
- Faulty fuel system: This refers to the injectors, fuel lines, pump, filter, and pressure regulator. There will be hesitation if any of these components break down.
- Faulty ignition system: If your rotor, wiring, or spark plugs need to be replaced, your engine can occasionally lose power and tremble.
- faulty sensors Your engine’s mass airflow sensor, caras oxygen sensor, and manifold absolute pressure sensor all control airflow. An incorrect air to fuel ratio can be brought on by any one of these.
- Gas recirculation valve: This valve is in charge of diverting exhaust gas into the manifold so that it can combine with fuel. If it is broken, the engine will hesitate at low RPMs.
