My car stutters after driving it for a few minutes
My car have been sitting in the garage for 8 years. When i decided to start driving the car i had to replace the fuel pump because the car wouldn't start. After replacing the fuel pump the car started up. One week later the car started stutter starting. A diagnostic test was done on my fuel pump it was at 50psi instead of 60psi where it should be. I hesitate to replace the fuel pump because the car start up fine in the morning but stutter start after i drive it a while. Do you think something else is causing the fuel pump to lose pressure?

Experienced mechanics share their insights in answering this question :
This may also be caused by what is called the fuel pressure regulator. This is a unit that helps to maintain the fuel pressure at the proper level. When this is not working properly, the fuel pump may be pumping properly, but the fuel may not arrive at the fuel injectors at the proper psi. When this happens, this can cause a lean fuel condition which may cause the car to hesitate, misfire or stall. I would recommend having an expert from YourMechanic come to your location to diagnose your fuel pressure.

What could the problem be? There are a range of reasons why your car is juddering when you accelerate. Your vehicle could have dirty fuel injectors, a damaged fuel pump, a blocked catalytic converter, a faulty mass airflow sensor, broken spark plugs, or even an accumulation of moisture.
Fuel pump failure will cause significant driving performance issues within your vehicle. Lower gas mileage is the best-case scenario for a bad fuel pump. Fuel pumps that fail during a drive will cause a vehicle to stall or break down. If your fuel pump`s deficiencies are severe enough, your car may not start.
Hi there – if your car stutter-starts, but runs fine once it is running, you probably have a problem with the fuel system check valve. This valve maintains some fuel pressure in the system so that your car starts faster once the key is turned to “Start”.
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.
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.
Low fuel pressure can lead to engine misfires, low acceleration, rough idles, and engine stalls. If your check engine light is on and your car has been stalling out, you may have a fuel pump failure.
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 you`re in motion at low revs your car judders, until you accelerate up to a higher speed and move into higher gears. What might be causing this? Worn engine mounts. Loose or worn engine mounts, which hold the engine to the chassis, could be the culprit.
Three of the most common causes of heavy equipment low fuel pressure are a faulty regulator, a fuel pump malfunction or problems with the fuel lines.
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.
The short answer is no. There is no known cure for stuttering, and like any other speech disorder, it requires therapy and practice to treat or manage it, and while some people report that their stutter suddenly “disappears”, for most adults who stutter they will continue to do so for their entire lives.
Engine vibration can be a result of many different issues in your vehicle, but when it occurs at a low RPM it usually is the result of faulty spark plugs, poor fuel pressure, or even an engine misfire.
Dirty Air Filters
The air filter functions to prevent dirt and debris in the air from entering the engine. If it`s dirty, it could restrict airflow to the engine, thus reducing the amount of oxygen that the engine gets. This causes an uneven oxygen-to-fuel ratio in the engine which leads to misfiring and car jerking.
A sputtering engine means that it is not achieving full combustion. It could be the sign of a very simple problem or it could be a symptom of a much more concerning engine, fuel system or exhaust system issue. The most common reason why an engine sputters is when you are about to run out of gas.

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.

Oil leaking from under car and "remote control car" sound when car is first started for a few minutes until it warm up.
ANSWER : Hello,
There are a number of things that could make an engine noisy when starting up. Depending on the specific type of sound you are referring to, this will determine how to properly diagnose. If there is a bit of a hissing sound, this may be a sign of a vacuum leak. If this is more of a shrieking sound, this may be a sign of a worn out or out of adjustment serpentine belt. If there is a bit of a howling or growling sound, this may be a sign of a worn out or low on fluid power steering pump. A rattling or pinging sound may be caused by an ignition problem. An engine can ping (or knock) due to an improper combustion process. A "spark knock" is the result of combustion occurring too early. Early combustion can occur from carbon buildup inside the combustion chamber, a lean air/fuel mixture, and advanced ignition timing (spark plug firing too soon). A clattering type sound may be a result of improper lubrication in the valve train which could be a more serious problem and should be addressed as soon as possible. I would suggest having an expert from YourMechanic come to your location to diagnose and inspect your vehicle to ensure everything is in proper working order.

My car will only shift into reverse and neutral, can’t get it into the drive gear
ANSWER : This may be a result of low transmission fluid or potentially a faulty transmission control module. A faulty transmission control module may cause a delay in acceleration or erratic shifting of gears. The transmission control module has various sensors such as vehicle speed sensors, wheel speed sensors, throttle position sensors, turbine speed sensor, and transmission fluid temperature sensors that all direct information to it in order for it to perform it’s function. Other functions controlled by the TCM are components such as a kick down switch, traction control system, and cruise control module. Any of these may also affect the way the transmission control module performs and controls the transmission and the shifting of your vehicle. I would suggest having a professional from Your Mechanic come to your location to properly diagnose your transmission problem.

Car will not move after driving for 2 minutes
ANSWER : Hi there. According to what you’ve described, this sounds like a slipping transmission. When the internal clutch packs become worn or damaged, the friction material is reduced and slipping can occur. Once the transmission begins slipping, it can overheat the fluid and continued use will further the condition. You have some options if you want to keep the vehicle: replace the transmission with a used unit, replace the transmission with a new unit, or have the transmission rebuilt.
I strongly recommend you acquire a qualified technician to perform any of these options. Your mechanic has several available technicians that can assist you with an acceleration inspection and provide an estimate and direction for repair.
