Experienced mechanics share their insights in answering this question :
The engine needs the proper fuel and spark to operated correctly. You may want to see if you notice any lights illuminated on the dashboard. The possibilities of this condition are an engine misfire, which could be caused by a fault in the ignition system (spark) or the fuel system. The fuel system needs the correct the operating pressure in order to function properly. If you want to have this checked, a technician from YourMechanic can come to your car’s location to diagnose your car’s sputtering issue and let you know what needs to be done.

One of the most common causes of a sputtering engine is an issue with the vehicle`s fuel system—the filter, pump, and injectors. These three critical components work together to ensure fuel flows smoothly from the fuel tank to your engine`s fuel injectors, and then pumps into the engine evenly.
A sputtering engine is a sign of a lean fuel mixture in the combustion chamber. This can happen if you have a clogged somewhere in the fuel system that impedes the delivery of fuel into the chamber. For example, your fuel filter or fuel lines might be clogged.
This symptom often points to an issue with either your exhaust system, fuel or dirty or worn out parts. In internal combustion running vehicles, and incomplete combustion will cause a sputter. And while a sputtering engine might not seem like a serious issue, it often results in an expensive repair when ignored.
FUEL INJECTORS

When your fuel injector becomes clogged with carbon, it isn`t able to spray enough gas into the engine`s intake manifold or cylinders, which causes sputtering.

Finally, as mentioned above, if your oxygen sensor is going out you may experience engine performance problems such as sputtering and surging. The sputtering is caused when the engine control unit puts too much air in the combustion chamber.
If you are experiencing jerks in your car when accelerating, it might be due to a few reasons. The first reason is that the throttle pedal is not positioned correctly. The second is a result of the throttle cable being too tight or too loose.
Since the information relayed by the crankshaft sensor into your car`s on-board computer is used to determine the proper spark timing, a bad crankshaft sensor will relay wrong readings into the computer, affecting the fuel injection process and causing your car engine to sputter.
Technician: Rough idle is another pattern failure of a MAP sensor. Other symptons could be a loss of power or sputtering engine conditions. Even if you have no obvious surging or sputtering, if the engine has a faulty MAP sensor, the idling will likely be rough.
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.

Moisture gathering in your car`s distributor cap can cause your car to jerk while you are accelerating, as this will cause your engine to misfire. This can happen easily when you are parked outside in cold weather. The best way to prevent this is to park in a warm dry spot on cold and wet weather days.
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.

If the engine isn`t getting enough gas, it will sputter at high speeds. If the engine isn`t getting enough gas, it could be a clogged fuel filter, clogged fuel lines, or problems with the fuel pump. Fast Lane Automotive explains engine sputtering is just one sign of a failing fuel pump.

Won’t shift out of first unless you let go of gas but it will shift back down and never grab second
ANSWER : If you have all the drive shafts in the front and rear, then you will damage the transfer case or one of the axles if you drive the vehicle and engage the front end. The two different gear ratios will do this. As far as the transmission goes, you have a problem with the governor inside the transmission and may have bad second gear parts. Have a mechanic pressure test the transmission and diagnose the shifting issue for you.

My gear shift doesn’t shift to any other gear its stuck on neutral. I open the gear assembly and I can pull a lever which allows me to move it.
ANSWER : Hi there. The shifter interlock solenoid is not working and needs replaced. The shifter interlock solenoid makes the shifter lock in place so it does not move if you accidentally move it into another gear. If you need further assistance with your shifter not working, then seek out a professional, such as one from Your Mechanic, to help you.

Won’t shift past 2nd gear . It drives normal to 2nd gear but wont shift into 3r – 2000 Ford F150 4×4
ANSWER : Hello – I don’t think this is related to switching back to 2WD per se. There is a shift position sensor on the side of the transmission, and it’s possible that the snow activity caused moisture and/or dirt to get into the sensor. I would recommend a transmission inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

The car doesn’t shift into first gear while it works fine in reverse
ANSWER : The problem could be that the internal transmission pump is weak, or the transmission clutch seals are leaking. It sounds like the transmission will need an overhaul.

I recommend having a transmission mechanic test the pressures and diagnose the problems to verify whether you need an overhaul with a new torque convertor.

I got sound when I shift to 3rd gear and it’s get hard to put shift to second gear when car is in 3rd gear.
ANSWER : Hello. It sounds as though the synchronizers in the transmission, which are used to adjust transmission internal gear speed when upshifting or downshifting are possibly worn out or you are shifting a bit too fast. It is also possible that the clutch is not releasing fully when you press the clutch pedal. In some conditions, utilizing synthetic gear oil in the transmission can help the quality of gear shifting. If the clutch is not fully releasing an inspection of the clutch hydraulics is a good idea. I would recommend having an inspection of the hard shift completed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost for repairs.

it doesn’t want to shift into reverse sometimes and it doesn’t want to shift up to the next gear without letting off on the gas why
ANSWER : Hello. It sounds like the car has a valve body issue. Most of the time, this is caused by one of the valves getting hung up in the transmission valve body or one of the solenoids sticking. I usually scan the computer for codes first to see if anything comes up. If not, then I test the pressures of the transmission to see if it is an electrical issue or a mechanical issue. Either way it would be best for you to get some help from a transmission specialist with this. If you would like to have this checked, a qualified professional from YourMechanic can come to your home or office to diagnose the shifting issue and pinpoint the problem.

Transmission intermittently won’t shift to next gear
ANSWER : It is very possible that the transmission may require a full rebuild or a replacement in order for it to perform properly. Although you are able to shift into other gears, if certain gears are not working correctly, transmission damage may be the cause.

If the transmission has already been diagnosed by the dealer that it needs replacement and the transmission is still not shifting properly, it is unlikely that the transmission will get any better without replacement.

It does not hurt to attempt any reset procedure that may be available, but it is also unlikely that a reset of any kind will resolve transmission issues. Small things to check before replacing the transmission if possible would be the fluid level and any trouble codes that may have been stored due to the issue your transmission is causing.

If any codes exist, this may lead you to other possible parts inside the transmission that may be able to be replaced and have your transmission working again as it should. You can get a second opinion from an local expert, such as one from YourMechanic, in order to diagnose your shifting problem and advise you on the next steps.
