Hyundai Rena 1 4 engine with weak throttle

I am the same as you in 2011 Hyundai Rena, and you said the same fault phenomenon, the spark plug was replaced, the throttle, fuel injector, intake manifold carbon deposition cleaned, did not solve the problem, and finally replaced 4 ignition coils, it is recommended that you change the spark plug and ignition coil The problem is absolutely solved! Don't listen to the flickering of car repairs.

I suggest starting in three areas. One aspect is to check the lack of air intake from the intake and exhaust aspects. The air intake system may mainly be the throttle, whether it is dirty, if it is dirty, it can be simply cleaned.

In terms of exhaust, it may be that the exhaust is blocked, and it may be that the three-way catalytic converter is blocked, which should be opened to the 4S store for inspection.

On the other hand, remove the spark plug to see the gasoline combustion. The spark plug has a long time, a large jump gap, a weak ignition, and there is no whitish at the bottom of the spark plug. If it is whitish, it means that the oil is not good.

The third aspect is to check whether each cylinder is working properly and whether the cylinder pressure is enough. There is also the possibility that the brake light switch is broken or working poorly, which can also cause weak acceleration.

I hope my advice will help you with your car. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello. In this case, it is recommended to check whether the fuel injector is poorly atomized or the spark plug gap is too large, the carbon deposit is too much, and the fuel pressure is insufficient. Clean the throttle valve, fuel injector, replace the spark plug, and clean the three-way catalytic converter.

Replace the fuel filter. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Summary. Hello. Friend.

Causes and solutions to this situation:

1. The quality of gasoline is not up to standard. The poor quality of the gasoline leads to insufficient combustion of the mixture when the engine is working, and the engine fault light is on.

2. Oxygen sensor failure. The oxygen sensor is damaged or the plug is damaged or loose, resulting in the mixture being too thin or too thick, and the fault light is on.

3. The air flow sensor is faulty. If the air flow sensor or line fails, the ECU cannot receive the correct air intake signal, resulting in the inability to control the fuel volume and affect the normal operation of the engine.

This situation is related to the oil that has just been added, which is caused by the substandard quality of gasoline.

Check out your friends, I hope it can help you.

Hello. The reasons for this situation and how to deal with it: 1. The quality of gasoline is not up to standard.

The poor quality of gasoline leads to insufficient combustion of the mixture when the engine is working, and the engine fault light is on. 2. Oxygen sensor failure. The oxygen sensor is damaged or the plug is damaged or loose, resulting in the mixture being too thin or too thick, and the wheel code is faulty and the light is on.

3. The air flow mold inductor is faulty. If the air flow sensor or line fails, the ECU cannot receive the correct air intake signal, resulting in the inability to control the fuel volume and affect the normal operation of the engine. 4. Carbon deposition in spark plugs.

Carbon deposition in the spark plug leads to poor engine work, resulting in difficult starting, unstable idling, poor acceleration, rapid refueling and tempering, excessive exhaust gas, and increased fuel consumption. This situation is related to the oil that has just been added, which is caused by the substandard quality of gasoline. Check out your friends, I hope it can help you.

I hope you can give me a thumbs up, your thumbs up are important to me, thank you.

There is also a shake in the exhaust pipe, if it is a gasoline problem, Bu Answer is not to change the standard gasoline, socks, can not continue to use up the oil in the tank or simply change the gasoline.

Hello. My friend needs to change the gasoline in this situation. Don't continue to use the oil in the tank. Hope it helps.

Hello, the car throttle can not be added, there is a feeling of frustration, it is recommended to do the following aspects of inspection: first, this is more common is the car Mu Hu car spark plug aging or ignition coil damage caused by this situation, this can go to the repair shop to disassemble the spark plug, check the amount of spark plug clearance, if the amount of noise is too large, or the wear is more serious, generally replace the spark plug can solve the problem. The inspection of the ignition coil needs to use the computer to read the specific fault code, if the corresponding cylinder has a misfire, it is generally a problem with the ignition coil.

Second, the engine has too much carbon deposit, resulting in weak speed, and it is recommended to clean the engine carbon deposit, especially the throttle inlet and cylinder carbon deposit. The carbon deposition in the cylinder is mainly the carbon deposition of the piston position and the valve base position, and then rematch the throttle to the resistance bureau,! Third, the fault caused by the failure of the oil circuit, this needs to detect whether the fuel supply pressure of the gasoline pump is normal, if the oil supply pressure is unstable, it is necessary to replace the new gasoline pump in time.

Summary. Hello, dear, I'm honored to answer for you! <>

2016 Hyundai Rena engine hangs.

Three or four acceleration powerless, hanging.

The normal reason for the first and second gears is clutch slippage, generally clutch slippage, and this situation requires the change of transmission oil and clutch plates. If the speed does not go up, it is possible that the three-way catalytic converter is blocked, and the fuel pressure and spark plug gap need to be checked.

Summary. Hello, happy to answer your <>

The Rena car is underpowered and stalled due to fuel ** issues: Check that the fuel system, including the fuel pump, fuel filter, and fuel injector is working properly. Insufficient fuel supply can lead to low power and stalling.

Ignition System Issues: Make sure the ignition system is working properly, including whether the ignition coil, spark plug, and spark plug wire are working properly. Ignition system failure leads to insufficient power and stalling.

Air Intake Problems: Check if the air filter is clogged and if the air flow sensor is working properly. Insufficient air** makes it difficult for the engine to operate.

The Rena car is not powered enough, what is the matter with the stalling.

Hello, happy to answer your <>

The reason for the lack of power in the Rena car and the stalling is the fuel ** problem: check whether the fuel system, including the fuel pump, fuel filter and fuel injector is working properly and slippery. Insufficient fuel supply can lead to low power and stalling.

Ignition System Issues: Make sure the ignition system is working properly, including whether the ignition coil, spark plug, and spark plug wire are working properly. Ignition system failure leads to insufficient power and stalling.

Air Intake Problem: Check if the air filter car leak is clogged and if the air flow sensor is working properly. Insufficient air** makes it difficult for the engine to operate.

These problems are solved, or the power is insufficient, and the flame is out.

What about your air filter, how do you check.

Also checked. Kiss <>

Improper valve adjustment and low-pressure oil pump failure all lead to engine performance degradation and stalling.

Expansion: An oil pump is a mechanical device used to transport liquid fuel lubricants from one place to another. It is mechanically or electrodynamically driven, and the chain generates a certain pressure that allows the liquid to flow.

Summary. Hello, don't click to end, I'm textual to give you the full answer, 2-3 minutes.

Hyundai Rena idles 4-cylinder without misfire, and runs 4-cylinder misfire.

Hello, don't click to end, I'm textual to give you the full answer, 2-3 minutes.

Hello, if the 4-cylinder has been on fire, it proves that the 4-cylinder combustion is not good, first check the fuel injector to see if there is a leakage of the sock digging or misatomization, followed by the cylinder pressure and internal carbon deposition to see if there is too much, the intake system to see if there is air leakage, and the spark plug ignition coil to see if there is a problem.

The same goes for burning gas.

Well, it proves that there is a problem with the cylinder pressure, flashover and system to see if there is air leakage.

That's it after changing the timing.

The valve is also tightened, and the cylinder pressure is normal.

In this case, the timing system and camshaft will be checked to see if there is any abnormal wear.

There is nothing to do with the VT wheel.

If there is no wear and tear, if the injector and the cylinder pressure are normal, if there is a problem with the variable wheel, it will also cause it.

Insufficient fuel**: If the fuel ** is insufficient, it will cause the engine to fail to work normally, and there will be problems such as unsmooth acceleration and weak acceleration. Air filter clogged:

If the air filter is clogged, it will lead to insufficient air flow, which will affect the performance of the engine and make acceleration not smooth. Ignition system failure: If the ignition system fails, it can lead to poor ignition of the spark plug, which can affect the performance of the engine and make acceleration unsmooth.

We recommend that you first check that your vehicle's throttle valves, fuel** and air filter are in order. If these parts are normal, it is recommended that you go to a regular car repair station or repair shop for a comprehensive inspection and repair to rule out other potential problems.

Hyundai Rena suddenly can't add fuel and cut off fuel while driving! Release the throttle and press it again, and ask for an answer.
