Acura TL Hesitation During Acceleration

by Christine Chan February 24, 2023

A common complaint of the Acura is that there is a slight delay in acceleration.

The easiest quick fix is to add a throttle response controller. This device attaches directly to your accelerator to amplify the electrical signal to your engine throttle control unit (ECU). The signal is adjusted using a remote or a smartphone app.

Honda motor company

Honda motor company issued a service bulletin to address the problem in 2007-2008 Acura TL vehicles. According to the bulletin, the cause of the hesitation during acceleration can be traced to the engine's computer software. The software may cause the engine to misfire, which in turn can cause hesitation during acceleration.

Honda recommends that the software be updated to the latest version to fix the problem. In some cases, the problem may also be caused by a faulty sensor, and replacing the sensor may be necessary.

If your Acura TL is experiencing hesitation during acceleration, it is recommended that you take it to a qualified mechanic or Honda dealership as they can get the trouble codes and help you diagnose the problem.

I hope this helps!

Transmission fluid

Transmission fluid is the lifeblood of your transmission. it keeps everything lubricated and running smoothly. if you don't have enough trans fluid in your transmission, it will cause the gears to slip and grind, and eventually, fail.

If you're experiencing hesitation during acceleration, it could be a sign that your tranny fluid is low. check your transmission fluid level and top it off if necessary. if that doesn't solve the problem, you may need to have your transmission flushed and refilled.

Check engine light

Check engine light may come on due to a number of reasons. When the light comes on, it means that your car's computer has detected an issue with one or more of your car's components. The light will usually come on when the engine is first started, and then go off after a few seconds. If the light stays on, it means that there is a problem that needs to be addressed.

Automatic transmission

Automatic transmission vehicles may experience a slight hesitation when accelerating from a stop. Our technicians tell us this condition may be caused by an accumulation of sludge in the oil pan. Draining and refilling the transmission with fresh fluid may correct this condition.

Manual transmission

Owners of manual transmission vehicles may complain of hesitation when shifting from first to second gear or an abnormal noise may be noted. Our technicians tell us these problems may be caused by a defective second-gear synchronizer assembly. Replacing the damaged component should correct this condition.

Common Questions for Acceleration Hesitation

What causes engine hesitation on acceleration?

A number of factors can cause an engine to hesitate during acceleration, including:

1. Dirty or old spark plugs

2. Faulty fuel injectors

3. Clogged air filter

4. Worn-out oxygen sensor

5. Loose or damaged vacuum hose

6. Intake manifold leak

7. Ignition system problem

8. Bad torque converter

9. Exhaust system restriction

10. Weak fuel pump

How do you fix engine hesitation during acceleration easy fix?

If your car is experiencing engine hesitation during acceleration, there are a few potential causes. One possibility is that the fuel injectors are dirty and need to be cleaned. Another potential issue could be a problem with the mass air flow sensor. If the sensor is not functioning properly, it can cause the engine to run lean, which can lead to hesitation during acceleration. Finally, a problem with the throttle body or intake manifold could also be causing the hesitation. If you are unsure of what is causing the problem, it is best to take your car to a mechanic for diagnosis and repairs.

Can bad spark plugs cause hesitation when accelerating?

Bad spark plugs can cause all sorts of engine performance issues, including hesitations during acceleration. If your spark plugs are old or fouled, it's a good idea to replace them. This is especially true if you've noticed any other strange engine behavior lately. If replacing the spark plugs doesn't fix the problem, there may be another issue at play.

How do I reset my Acura TL ECU?

Acura TL owners may notice a hesitation during acceleration from a stop. This may be caused by the ECU (engine control unit) being out of sync with the engine. The ECU can be reset by disconnecting the battery for at least 30 seconds. Once reconnected, start the engine and let it idle for a few minutes to allow the ECU to relearn the engine's idle parameters. If the hesitation persists, take your vehicle to a qualified mechanic for further diagnosis.

What causes a car to struggle to accelerate?

There are a few different things that can cause a car to struggle to accelerate. If the problem is with the engine, it might be something as simple as a spark plug that needs to be replaced. If the problem is with the transmission, it might be something as simple as a dirty filter. If the problem is with the fuel system, it might be something as simple as a dirty fuel injector. If the problem is with the electrical system, it might be something as simple as a loose wire. Whatever the cause, a trouble code reader can be a valuable tool in diagnosing the problem or at least narrowing down the possible causes.

What causes weak acceleration?

One possible cause of weak acceleration is a fuel delivery issue. If your car isn't getting enough gas, it will run slowly and lack power. Another potential cause is a problem with the ignition system. If your spark plugs are fouled or your wires are damaged, your engine may not be able to fire properly, resulting in weak acceleration. Finally, a clogged air filter can also lead to weak acceleration. If your filter is blocked, your engine won't be able to breathe properly, costing you power.

If you're experiencing weak acceleration, the best thing to do is to bring your car to a qualified technician for diagnosis. They will be able to pinpoint the exact cause of the problem and get your car running properly again.

Does Acura TL have transmission problems?

Yes, the Acura TL is known to have transmission problems. One of the common problems is transmission shudder, which can be caused by a variety of things, including low transmission fluid, dirty transmission fluid, or a faulty torque converter. You should check the transmission fluid level and condition first, and if it looks dirty, have it flushed and replaced. If the transmission is still shuddering, it's likely that the torque converter needs to be replaced. A software update may also be required.

Another common problem is that the transmission may hesitate when shifting gears. This can be caused by a number of things, including a dirty transmission filter, low transmission fluid, or a faulty shift solenoid. Some say premium gas may help.

Acura recommends changing the transmission fluid every 30,000 miles to help prevent these problems. You may need to change it more often if you drive in stop-and-go traffic or in extremely cold or hot weather.

If you are experiencing transmission problems, it's best to take your car to a qualified mechanic or Acura dealer for diagnosis and repair.
