Car is jerking for a while and then runs fine

I have a well-maintained car with around 150,000 miles on it. I have regular oil changes and fill the car with premium. Recently, the dashboard showed check engine light illuminated. The car has started skipping. Now the car is jerking like when the RPMs are very high. After waiting several minutes or while driving it, the car would start getting back to normal. I took it to a shop and was told it is a bad TCC solenoid. Is that serious? Would it damage the car if I drive with this issue? Thanks.
Experienced mechanics share their insights in answering this question :
The TCC is the torque convertor clutch solenoid inside the transmission. To get it replaced you would need to have the pan removed and the TCC solenoid tested and replaced.

If all your drive issues start to happen after about 45 mph, then I suspect the solenoid is the issue. There is some tests that would and should be done to verify the failure. This is done with a factory style scanner that can activate the solenoid manually to check to see if it operates correctly or the transmission has another problem. You may have a defective torque convertor or sensor problem that only a diagnostic test can reveal and isolate the failure. If you want to have this taken care of, a technician can inspect your car’s jerking issue and let you know what needs to be done.

How to Identify and Fix Common car Problems ?

The most likely problem is an engine misfiring from an ignition problem, such as a failed spark plug, plug wire, or coil problem. Some of these engines may also have problems with fuel injectors. I recommend having the Check Engine Light diagnosed by a certified mechanic, such as one from YourMechanic.
Clogged Fuel Injectors

If you hear your car engine stuttering, then the injectors may not be providing an adequate amount of fuel. To fix this, you should clean the injectors on a regular basis. Using a fuel injector cleaning solution might eliminate the issue of the car jerking.

Typically, a surging or jerking motion can be caused by an unbalance of air and fuel in the engine. Your engine needs the exact amount of an air and fuel mixture to properly perform the combustion process.
Blocked Fuel or Air Intakes

Your car moves as a result of this cycle. However, during acceleration, your car may jerk if the lines allowing fuel and air to enter your engine are blocked. In most cases, when one of these intakes is blocked, a check engine light will appear – never ignore a check engine light!

When your car jerks, stumbles or stutters while driving, it usually means something is interfering with the proper distribution and transfer of power from your transmission. Another example is if you`re driving a manual transmission and haven`t gained the feel of shifting for your particular vehicle.
This hesitation while accelerating can be the result of a number of issues, including something like a clogged fuel filter or even a broken fuel pump. Sometimes, something could also be wrong with the transmission.
When the transmission jerks between gears or the transmission is shifting hard, it should be taken as a warning that your transmission needs repair. When a transmission is shifting hard or slipping it`s time for an inspection.
If you`re driving at freeway speeds and notice your engine sputter or jerk, you may have a failing fuel pump. This problem is caused when the fuel pump can`t deliver a smooth flow of fuel to the engine; periodically, your engine receives only air when it was expecting to receive fuel.
It could have a failing mass air flow sensor, a failing throttle position sensor, a problem with the fuel pressure, or even an internal transmission problem.
An indication that a vehicle is not receiving the right mixture of air and fuel is if the vehicle jerks or surges forward at high speed. Several components of the fuel or air intake system could cause this jerking or surging sensation to happen. Issues within these systems can also cause fuel economy to worsen.
It`s extremely unlikely, but if the alternator has gone bad, and the battery is just about dead, the car COULD POSSIBLY jerk or surge right before it quits running because the battery can no longer supply enough juice to properly run the fuel pump, etc.
If you notice that your car jerks while you`re accelerating, this is an issue that you shouldn`t ignore. A jerking car is often a sign that your car will develop other problems if you don`t address this issue. Dirty fuel injectors are among the most common reasons for why an accelerator becomes jerky.
One of the most common causes of jerky acceleration is a dirty fuel injector. Your fuel injectors are responsible for pushing fuel into your engine`s cylinders. This means they control the timing and amount of fuel used to keep your engine running.
The short answer is yes. Engine oil is crucial in maintaining optimal performance by lubricating and cooling engine components. Neglecting regular oil changes can lead to increased friction, reduced efficiency, and potential engine damage, ultimately impacting acceleration.
The Vehicle Speed Sensor measures vehicle speed. When it fails the transmission can stop shifting or shift late and harsh. A bad VSS may also inhibit overdrive and the converter clutch.
A car that surges or jerks at high speed is potentially dangerous, especially in heavy traffic or in bad weather. If your vehicle jerks at high speed, you should stop driving it and have it inspected by a mechanic.
A common cause is a problem with the spark plugs or ignition system. Other potential causes include a blockage in the fuel line, a faulty oxygen sensor, or a problem with the mass air flow sensor. Vacuum leakages can also cause a delay in acceleration. A clogged air filter or low engine oil level can also be a cause.
A car that surges or jerks at high speed is potentially dangerous, especially in heavy traffic or in bad weather. If your vehicle jerks at high speed, you should stop driving it and have it inspected by a mechanic.
Normal idle speed for your vehicle, once the engine is warm, should be around 750 RPM (roughly). Two thousand RPM is significantly out of range high, even for a cold engine.
Car engine rpm increases as you press the accelerator, as does power — at least to a point. An engine doesn`t necessarily produce its maximum power at its highest rpm. Engine specifications typically present the peak horsepower figure followed by the rpm at which it occurs, such as 252 hp at 5,600 rpm.
Strong spark plugs help in quick engine ignition and can help in maintaining your RPM levels optimal. When your spark plugs become faulty, your engine needs to work more due to low combustion. Poor combustion makes your RPMs high and makes you slow down on acceleration.
A car that surges or jerks at high speed is potentially dangerous, especially in heavy traffic or in bad weather. If your vehicle jerks at high speed, you should stop driving it and have it inspected by a mechanic.
Old or worn-out tires are one of the number one causes of a shaking vehicle and often the easiest problem to fix when it comes to taking the shake out of your vehicle. Additionally, low pressure in your tires or uneven wear on the tires can lead to a shaky vehicle.

Hi, i was driving my car just fine today when all of a sudden it started jerking. it jerked a lot getting up to about 20mph then i
ANSWER : Hi there. I wouldn’t suspect that removing the battery has caused any problems. When your engine runs rough, it can be caused by multiple issues, ranging from a vacuum leak to fuel system component problems, and ignition system issues. I would recommend having one of our professional mobile mechanics come to your location and complete an engine is pulsating inspection. This will allow them to isolate the source of your issues and recommend the right repairs.

Power steering loss, no belts are turning but the car is running fine. I also have a soft pedal. Whats wrong with my car?
ANSWER : I have only seen this situation once in my 30+ years and it turned out to be a broken crankshaft pulley. Belts are driven by the engine. The crankshaft pulley spins the belts, which in turn spin the air conditioner compressor, power steering and water pumps, and the alternator. The vehicle should be towed to your local repair shop and not driven. Without the water pump spinning to circulate the coolant, the engine will quickly overheat and result in more extensive damage.

Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage
ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.

I have a mini r53 s (supercharged) runs fine but when car stop and AC is on for a wile car overheat
ANSWER : Your question makes me think of a case I ran into a few years ago. The owner had modified his car but when he installed his fans, one of them was wired backwards so the fan ran in reverse. The two fans were fighting each other which was just like having no fan at all, so the car heated up while it was sitting still then it cooled off when moving. Check the rotation of both the fans before you check anything else. If that’s OK, you may be able to track down the problem with a non-contact thermometer, follow the course of the coolant with the beam. The radiator should be about 30 degrees or more cooler at the exit than at the entrance. If you need help with this, contact Your Mechanic. They can send a technician to your home to check out your overheating problem and let you know what can be done for it.

Fuel EVAP line that runs under car is kinked how do I know if it is leaking? Also can I drive it like that if it’s not leaking?
ANSWER : Hi Ricardo. We answered your question earlier. However, if you didn’t receive the reply, here is what we stated earlier. In most cases, an EVAP leak will create an OBD-II trouble code. The best way to detect an EVAP leak is by having a professional mobile mechanic complete a check engine light inspection, they will be able to download the code and determine the source of the leak. That’s the best advice we can offer you. Thanks.

Car shuts off, won’t stay running
ANSWER : The most common problem on this vehicle is the fuel pump and fuel pump module. If you remove the rear seat that the fuel pump cover is, on the passenger side. Listen to the fuel pump when it is running and when the car stalls your fuel pump will stop running about three to five seconds before the engine dies. Then you’ll know if the fuel pump is the culprit or not.

You can try and replace the fuel pump module first then replace the fuel pump. However, the fuel pump can short the module out, causing both to be bad and would need to be replaced. If you need assistance with this, feel free to contact a certified mechanic who can diagnose your starting issue firsthand and help you fix it accordingly.

My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and
ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer.
