My Accord 2 4 feels underpowered for some reason

The main factors of insufficient power are as follows: 1) Reasons for fuel supply: due to the blockage of the ventilation hole of the fuel tank cap, the fuel tank switch, the fuel filter and the oil pipe between the fuel tank and the carburetor are partially blocked, which cannot meet the required amount of oil, resulting in the mixture being too thin and the engine working weakly.

Due to the long-term use of the air filter is not cleaned in time, the blockage, the lack of air volume will cause the combustible mixture to be too thick, so that the engine power will be reduced. The use of low-octane gasoline, the use of gasoline for too long, due to volatile deterioration resulting in too low octane number, easy to cause detonation, so that the engine power decreases. Carbon accumulation in spark plugs and other parts increases fuel consumption.

There is water and air in the oil circuit, which will affect the smooth flow of fuel. The muffler has too much carbon, which increases the exhaust resistance. 2) Reasons for the ignition system:

The ignition timing is inaccurate, and the ignition is too early, which causes the premature ignition and detonation of the combustible mixture. Due to the failure of the ignition system, the spark plug is broken or the spark plug spark is weak. 3) Compression pressure of the cylinder:

The serious wear of the piston, piston ring and cylinder causes the matching gap of the piston, piston ring and cylinder to increase, and the sealing becomes poor, resulting in the leakage of the cylinder head and the reduction of the cylinder compression pressure. Due to the poor sealing, the crankcase leaks, which reduces the suction power. Improper adjustment of valve clearance, misalignment of valve timing, and tight valve closure affect the cylinder pressure and reduce the power of the engine.

4) Engine overheating: due to various reasons, the combustion of the combustible mixture is incomplete, so that the carbon deposit in the combustion chamber is excessive, resulting in poor heat dissipation, and the engine load increases to produce overheating. 5) Too much or too little lubricating oil in the crankcase, the lubricating oil deteriorates or is dirty, and the lubricating oil passage is blocked, which affects the power of the engine.

Hello, the lack of power may be due to the carbon deposition of the throttle, please pay attention to check and clean. If my answer is helpful to you, please set it to.

Try cleaning the injectors.

Is it the engine or the transmission output? It is recommended to go to the 4S store for maintenance!

What is the reason why the acceleration of the Honda eighth-generation Accord is not good Fuel consumption is also higher than the original Three-way catalysis is no problem if the oil is blocked Ask for guidance from a master.

Honda eight-generation Accord acceleration is sluggish, and the fuel consumption is high, which may be caused by the engine oil circuit macro cavity system, which is often a problem for the car, such as blocked fuel injectors, oil pipe leakage, reduced fuel pump power, and blocked fuel filters. The main reason why the acceleration of the car is weak and the fuel consumption is high is that the engine does not have enough oil when accelerating, the combustion efficiency decreases, and the horsepower does not meet our requirements. In addition, the same is true for the air intake system, the engine needs air in addition to oil, if the air filter, throttle and other components are blocked or there is a problem, resulting in insufficient air intake, it will also cause the car to accelerate weakly and slowly.

Spark plugs are also a common source of failure, and if the spark plug is poorly ignited, it may lead to the problem of weak acceleration.

Isn't it "hanging bottles"? There is something wrong with this method.

If not, it may be that the air-fuel ratio is too high, let the 4s readjust, it is very simple and can be adjusted.

Japanese cars are like this、、、 can not be overhauled, once repaired, it will be over, all kinds of problems, untreated,

Has the computer matched it, it's a timing chain, and the chain is not in the wrong position.

Is it that the spark plug is not tight... If it's not tight, there may be a cylinder that doesn't work... = =

It is best to use a special tester HDS** data sheet before cleaning the water tank condenser.

According to your description, it is recommended to do computer matching.

The main reasons are as follows:

The oil pressure is not enough, the oil pump is not working well, and there is a blockage of the oil filter or the grease nozzle. When the speed of 3K rpm should be around 100, the acceleration is not weak, and it may also be a failure of the clutch part. Cold cars may be better, but as the temperature rises, there is a greater chance of frequent occurrence.

Throttle body sector, stuck or stepper motor failure. There is a possibility that the exhaust part or contact catalytic may be blocked. Electrical wiring is open or short-circuited, and the conduction is poor.

Throttle, also known as "damper", "throttle". Refers to a control device that controls the power (thrust) of an engine. In piston aero engines, the throttle controls the throttle opening of the carburetor to control the amount of cylinder filling, which determines the engine's power output.

Summary. Dear, glad to answer for you! The acceleration of the eight-generation Accord is weak, the oil can not be fed, and the reasons for the low speed are as follows:

Because of the addition of low-grade gasoline, there is a possibility that acceleration will not be effective, resulting in a decrease in engine power and an increase in fuel consumption. 3. Insufficient engine oil: if the engine oil is insufficient for a long time, the light one will have insufficient power and the fuel consumption will increase; In the heavier case, the piston strikes the door, causing mechanical damage to the associated connectors.

4. Gasoline pump failure: Gasoline pump failure and fuel filter blockage will also cause engine power to decrease. 5. There is a problem with the air filter:

If the air filter, throttle and other components are clogged or there is a problem, resulting in insufficient air intake, it will also cause the car to accelerate inability and slow acceleration, and there is a sense of frustration. 6. Problems with spark plugs: If the spark plug is poorly ignited, dripping or atomizing, it will also affect the acceleration of the engine.

The acceleration of the eight-generation Accord is weak, the oil cannot be fed, and the speed is low.

There was no obvious reaction to the oil.

Dear, glad to answer for you! The acceleration of the eighth-generation Accord is weak, the oil is not gone, and the reasons for the low speed are as follows: 1. Clutch slippage:

If the speed of the car does not go up, there is a high probability that the clutch will slip. 2. Add the wrong oil: because of the addition of low-grade gasoline, there may be a situation of weak acceleration, resulting in a decrease in engine power and an increase in fuel consumption.

Faulty gasoline pumps and clogged fuel filters can also cause engine power to drop. 5. Problems with the air filter: If the air filter, throttle and other components are blocked or have problems, resulting in insufficient air intake, it will also cause the car to accelerate weakly and slowly, and there is a sense of frustration.

6. Problems with spark plugs: If the spark plug is poorly ignited, dripping or atomizing, it will also affect the acceleration of the engine.

Extended Information: Based on the concept of "Advanced-Powerful" in the development and design of the eighth-generation Accord, which means the perfect blend of "forward-looking technology and agitated power", Honda Motor Co., Ltd. has developed a new technology platform that embodies the best interpretation of Honda's global DNA in terms of space design, safety, dynamic performance, handling and environmental protection.

Kiss, it is the oil pressure of the oil pump that cannot be reached.

1. It may be carbon deposits.

When there is too much carbon deposition in the engine, the ignition energy of the car will be greatly reduced, and the air intake efficiency will continue to decline, and the engine power will decrease, and then there will be a situation of guessing the acceleration weakness.

2. It may also be that there is a problem with the fuel system of the car.

3. This will also happen when the driver stops the hunger and fills the fuel that does not match the fuel.

4. When the vent of the automobile fuel tank cap is blocked, the oil pipe between the fuel tank switch and the fuel filter is plugged, and the oil volume will be insufficient, and if the engine mixture is too thin, the engine will be unable to accelerate.

5. It may also be that there is a problem with the air intake system of the car, and the air is also the power of the car.

** in the air filter.

After a long period of use, if it is not cleaned in time, there will be clogging, and when the air volume is insufficient, the mixture will be too thick, and the engine power will also decrease.

The Honda Accord has weak acceleration mainly because the engine does not have enough oil. The PGM-FL system and the AT-system were tested with a detector without fault codes. The speed of both the D position and the R position is 2500r min, which is normal.

The time delay test was carried out: the d position was the r position, and the response of each gear was normal. A basic inspection of the engine and automatic transmission was carried out, and the results were normal.

1.What is necessary for the engine to function properly: not only enough oil**, but also air. A clogged air filter, or throttle system, can cause insufficient air intake.

2.Look at the circuit system: The internal combustion engine is the fuel that needs a spark plug to ignite into the engine, so the quality of the spark plug directly affects the ignition state. Spark plugs are consumables and need to be replaced for a fixed number of kilometers.

There are many reasons for the acceleration weakness, the common one is that the oil pressure of the oil pump cannot be reached, and the piston ring. The valve and other seals are not tight (measure the cylinder pressure, the normal is between 6 and 8) and the spark plug flashover strength is also related. Also, clean the injector again.

I did the same before, I did throttle cleaning (3m), three-way purification, and changing the transmission oil (must be original), and now the acceleration of the car is all improved to carry the resistance!

Don't wash the fuel injector indiscriminately, most of the master's skills are not in place.

It is recommended to check whether the air intake is blocked and the exhaust is not smooth.

Hello friends, it is recommended to check oxygen sensing and three-way catalysis.

Honda Accord idle sometimes high and low, such a situation, it means that the Honda Accord engine idle motor sludge is too much, you need to clean the Honda Accord idle motor, you can remove this fault, clean the Honda Accord idle motor The specific operation steps are as follows:

1. Unplug the Honda Accord idle motor.

2. Unscrew the screws that hold the Honda Accord idle motor.

3. Take down the entire idle motor of the Honda Accord and prepare it for cleaning.

4. Spray the throttle cleaner along the round hole of the Honda Accord idle motor.

5. Use a long-bristled brush to brush back and forth.

6. After brushing, pour out the throttle cleaner in the Honda Accord idle motor.

7. Install the Honda Accord idle motor back in its original position.

Honda's idle motor is a blade type, and the general traveling car is an idle motor hairpin, and most people think that it can be washed with carburetor cleaner, which makes many car owners finally have to replace the idle motor. The correct way is to let the idle motor completely dry after cleaning, and then use the film to repeatedly dial the blades to see that there is no hairpin, if there is a hairpin, even if it is slight, the idle motor should be decomposed and cleaned, and wait for a little dry sewing oil, and then use the paddle to repeatedly dial the blades after installing the coil, until there is no hairpin phenomenon.

This first depends on whether the throttle idle horse has been cleaned, it may not be cleaned or leaked after washing, and the fuel injector throttle valve may not be repaired [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, this is a traveling car situation, but there is a reason for this situation, the throttle is too dirty, or it is a situation that occurs after you clean it [There is a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】
