Poor acceleration and low RPMs, engine bogs down until turbo kicks in.

I have a turbo boost problem. My car has poor acceleration and low RPMs in lower gears. It feels like the engine is bogging down until the turbo kicks in.
Experienced mechanics share their insights in answering this question :
I would enlist the help of a diesel technician to inspect your engine for any faults as well as the turbo. Any hoses that may have come disconnected or if any sensors have gone bad this can affect your engines performance. I would also recommend having the vehicle checked for trouble codes as the check engine light may be on. If any codes are found they may be beneficial in diagnosing your issue.

If your engine revs up as you press down on the gas but your vehicle doesn`t accelerate as much as you`d expect, you may be dealing with transmission slipping. If you`ve ever tried to accelerate on ice, where your engine revs but your vehicle goes nowhere, you know the feeling.
There are a few reasons why your car might be struggling to accelerate. It could be due to a problem with the timing belt, the spark plugs, or the fuel injectors. It could also be because you have a dirty air filter or a clogged fuel filter. The fuel system may also be low on fuel.
An engine bogs down in low end rpms if the valve overlap is too much, if it can`t build up compression, if the mixture is too weak, if the fuel isn`t atomised well, if the spark isn`t timed correctly, or if the spark is too weak. These are in general the only reasons an engine could bog down, at low rpms.
When you press down the accelerator pedal and get minimal output, it could mean you have a problem with your fuel system. The most probable issue is a clogged fuel filter. Your fuel filter works to ensure that dirt and debris do not get into the fuel system.
Trouble accelerating can come from a few different engine issues. These include, but are not limited to, dirty fuel injectors, low fuel pressure, and restricted airflow. A problem with the mass airflow sensor, throttle position sensor, or engine speed sensor can also cause a car to have difficulty picking up speed.
Culprits include a dirty fuel filter, clogged fuel tank strainer, clogged or failing fuel injectors, or a defective fuel pump. On most vehicles replacing the fuel filter is a DIY operation.
There are several causes for your car to lose power significantly while accelerating. The most typical causes of a car not accelerating while driving include a faulty sensor, contaminated fuel or air filters, or a faulty timing belt.
Most of the time this is triggered due to a problem within the transmission. Either minor like low or leaking transmission fluid, a loose or malfunctioning sensor or a major component problem.
The engine RPM drop when changing gears is often caused by a failed throttle position sensor (TPS). When in use, the cone of the TPS accumulates soot that prevents the correct rod movement. If a TPS works abnormally, the air-fuel mixture will not meet the requirements.
Higher revolutions per minute equate to more fuel burnt in the same amount of time and more power produced. Because of this, most consider higher RPMs racing RPMs. Running at lower RPMs equates to higher torque and thus lower horsepower, while making higher RPM power outputs less torque and higher top horsepower.
Clogged car air filter

If you have a dirty or clogged air filter, not enough air is getting into the engine for optimal combustion, and there will be a lack of power when you are trying to accelerate, especially on Diesel vehicles.

Yes. While the damage may seem small initially, the longer you drive with a bad oxygen sensor, the worse the damage will become. Eventually, you may experience rough idling, poor acceleration, engine misfires, an illuminated check engine light, and failed emission tests.
Worn Transmission Fluid (Automatic Transmission)

Over time, the transmission fluid gathers dirt and grime. This can cause the engine to run roughly, stall or fail to accelerate when you press down on the gas pedal. You may need to have a transmission fluid change before more damage is done.

The most common problem is a faulty fuse. In modern vehicles, engine idle speed is most often controlled by the idle air control (IAC) motor. This can be impacted by bad fuses in many different electronic systems in your car. Next, your high idling could be caused by a computer malfunction.
Fuel Filter Clogging

Another reason for your car not accelerating on high RPMs, regardless of high RPMs or not, is a dirty or even clogged fuel filter. Fuel filters are installed in a car`s fuel system to filter out the dirt and the gunk in fuel.

I would also recommend having the vehicle checked for trouble codes as the check engine light may be on. If any codes are found they may be beneficial in diagnosing your issue.

Turbo VS. Non-Turbo Valve Cover Gasket
ANSWER : Hi there. Looks like the gaskets are the same for the turbo and non turbo engines. I recommend asking the local parts store for to see a valve cover gasket for the non turbo engine and a gasket for a turbo engine and compare the two gaskets. If the gaskets are the same material and have the same design, the go for the valve cover gasket that will fit your budget. If you need further assistance with the valve cover gasket, then seek out a professional, such as one from Your Mechanic, to help you.

Rattling noise from engine bay when acceleration pedal is pressed to keep RPM constant 2010 Honda Fit
ANSWER : Hello. Most of the time this is caused by the timing chain making noise in the engine. I will usually check the oil and replace it with the right oil and filter to see if it helps. A poor quality filter or the wrong oil can cause this. If the oil is fine then the timing chain itself may be failing or it may be a tensioner issue. If the chain seems fine then the noise may be coming from the exhaust if there is a loose heat shield. If you want some assistance with this, consider YourMechanic, as a certified mechanic can come to you to [diagnose where the rattling is coming from] https://www.yourmechanic.com/services/loud-squealing-or-rattling-is-coming-from-engine-inspection

The engine of the car runs, but when I push the gas pedal it does not accelerate, and the engine does not rev.
ANSWER : Hello. It sounds like you may have an issue with your throttle position sensor. This sensor sends a reference voltage to your power-train control module, which uses that to determine ignition timing and fuel trims. If the power-train control module is not detecting the proper signal from the throttle position sensor, the engine may not accelerate properly. It’s probably a good idea for you to have a professional mobile mechanic come to your location and complete a car is slow to accelerate inspection first, so they can pinpoint what is causing this issue to occur and they will recommend the right repairs be completed.

When accelerating, engine shuts down
ANSWER : Hello. From the symptoms you are describing, it would appear that the vehicle is having some sort of serious engine performance issues. A few things I would check on are the fuel and ignition system. The sound you describe from the tailpipe may be a misfire, perhaps related to a fuel system issue. A weak fuel pump or a clogged fuel filter can starve the engine of fuel, which can cause misfires or stalling due to a lean condition. Stalling can also be caused by a wide variety of other issues, such as vacuum leaks, and even ignition problems, so a proper diagnosis of car stalling by a certified technician from YourMechanic is recommended to determine what the exact cause of the issue may be.

PO341 code – cruise control kicks off, engine light and vsa lights go on.
ANSWER : There could be an issue with the cruise control switch and the brake switch. The VSA light refers to the brake system and the light maybe coming on for the brake switch not functioning properly causing the cruise control switch to disengage. The code P0341 refers to the camshaft position sensor, which could be coming on for the sensor malfunctioning. If the camshaft position sensor is not reading properly, then the cruise control will disengage as the engine is not in time correctly. If you need further assistance with your cruise control disengaging on its own, then seek out a professional, such as one from Your Mechanic, to help you.

Can front wheel drive car engine power rear wheel drive
ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.

Car sometimes give me acceleration and power issues. Engine power reduced message and engine light appear intermittently.
ANSWER : It is possible that your vehicle’s PCM has failed. This is somewhat of a common problem amongst many GM vehicles. If the computer has failed, this could be one of the reasons that no trouble codes are appearing and the fact that the problem is intermittent. It is possible that the computer is somehow getting overheated and by stopping the vehicle for a short period of time, the PCM cools down allowing the vehicle to run again. I would recommend having your PCM tested for proper function by a certified technician with experience in computer diagnostics.
