When try to give my car a lot of gas at once it bogs down and wont trys to shift

When you go to take off in it it is usually alright but once you get to like 25 mph you have to ease on to the gas because if you push it to much at once it bogs the engine down and wont really do anything unless you slowly ease into it. What would this be?

Hi There,
It sounds like you may have a fuel starvation problem due to a lack of sufficient fuel pressure. This can happen when the pump itself is not working properly or when the fuel pressure regulator is not maintaining the proper fuel pressure in the fuel system causing the engine to starve for fuel. This can also happen when there is insufficient connectivity to the fuel injectors which can cause an intermittent fuel spray pattern into the intake system resulting in a lean fuel condition or the motor otherwise starving for fuel. I would recommend having an expert from YourMechanic come to your location to diagnose your fuel system.

How to Identify and Fix Common car Problems ?

If your car is bogging down when you try to accelerate, it could be due to a clog in the fuel filter. The fuel filter is responsible for filtering out impurities from the fuel before it reaches the engine. over time, the fuel filter can become clogged with debris and dirt, restricting the flow of fuel to the engine.
There are a few reasons why your car might be bogging down when accelerating. One reason could be that your engine is low on oil, which is causing it to seize up and not work properly. Another possibility is that your spark plugs are dirty or worn out, which is preventing the engine from igniting the fuel properly.
In cases where there is too much fuel being provided (i.e. a leaking fuel injector), this may cause the engine to bog down and produce a fuel smell and occasionally, emit a bit of black smoke from the exhaust or cause problems with starting.
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.

Here are some the main causes for a sudden drop in gas mileage: Bad oxygen sensor and air filters-in all forms will affect the fuel mixture and your fuel efficiency. Bad or misfiring spark plugs-will result in poor performance and subsequent lack of power will cost you fuel efficiency.
A loose spark plug causes bogging because it doesn`t reach far enough into the combustion chamber to ignite all the fuel. A spark plug can become loose from vibration over time, or if it wasn`t properly tightened to begin with.
Why Does My Car Have Sluggish Acceleration? Faulty sensors: bad oxygen sensor, crankshaft sensor, MAF sensor, Camshaft Position sensor, or any sensor relative to the EFI system.
What would cause engine to bog down when accelerating but run normal at idle. seems to be either starved or flooded with fuel. and check the vacuum line going to the fuel pressure regulator for splits,holes,cracks,dry rot.
It could be due to a problem with the throttle body, gas tank, spark plugs, or the ECU. The fuel pump may also be failing. It could also be because you have a dirty air filter or a clogged fuel filter. The check engine light may also be on, which indicates that there is a problem with the engine.
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.

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.
Obeying the speed limit, accelerating and braking gently and gradually, and reading the road ahead can improve the fuel economy of your vehicle by 15%–30% at highway speeds and 10%–40% in stop-and-go traffic. Driving more sensibly is also much safer for you and others.
Pressure Sensor: The most common type of pressure sensors used for fuel level measurements is hydrostatic type sensor.

Overheating. Repeated overheating of the spark plug tip can cause the plug to prematurely fail. Overheating can be caused by many things like pre-ignition and a malfunctioning cooling system. Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail.
A good spark will be blue-white and will be plainly visible in daylight. If a good spark is present, the problem is probably not in the ignition system. Check the fuel system and/or stark timing. Weak sparks are orange or red and may be hard to see in daylight.
Fuel Pump: The fuel pump in most modern vehicles sits inside the fuel tank and pumps fuel up to the engine. If a fuel pump cannot provide the correct pressure, fuel may have difficulty making it to the engine. A vehicle that hesitates while accelerating or while driving up a hill may have a weak fuel pump.
Loud popping, knocking, and stuttering noises from the hood of your vehicle are cause for concern, and could be a sign of major engine damage.
Knocking, backfiring, hissing, spitting and popping are noises that can occur when there is an abnormality in the combustion flow. If you hear strange noises from the engine, schedule an engine service as soon as possible! Engine Stalling!
There are several problems which could cause this behavior, such as a bad throttle position sensor, fuel supply issues (low fuel pressure), or a dirty or bad mass air flow sensor. Problem codes will narrow the cause more quickly, and help avoid replacing parts that are not the problem.
Fuel lines, dirty air filters, and throttle body issues can all cause a delayed throttle response. You can avoid this issues by installing a Throttle Response Controller. Engine response time will be improved, and you`ll enjoy driving your car more.
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.
Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low.

Car has been sitting without gas for about a month and now when I try to start it, the starter works 100% but the car wont turnove
ANSWER : Hi there. It is possible that the lack of fuel in the tank may be causing the pump to have difficulty picking up the fuel. However, it is more likely that the fuel pump may be damaged, especially if there was no fuel inside the fuel pump or fuel lines. However, it could be something completely different causing your issues, so it’s probably a good idea to have a professional mechanic complete a car is hard to start inspection to isolate the source of this problem.

Charging warning light comes on when i turn the key and try to start the car and the car want start but when someone tried to give
ANSWER : Hi there:

If you recently replaced your battery, the issue may be caused by a malfunctioning alternator or other electrical component that comprises the charging system on your Nissan Sentra. The best way to find out which item specifically is faulty, is to have a professional mobile mechanic complete a car is hard to start inspection. This will allow the mechanic to determine the precise source of what’s going on with your Sentra and recommend or complete the right repairs.

If I put my car in drive and push on the gas it wont shift to second unless I let off the gas. If I drive it in overdrive it shift
ANSWER : Hello, the concern you have I strongly advise not to drive. The issue needs to be addressed, the vehicle will become inoperable. The automatic transmission has 3 systems; electronic, hydraulic, and mechanical. What describe could be an internal mechanical failure with transmission. The electrical system which includes the module, will go into a default mode if there is a failure with it. This mode allows forward gears and reverse depending on what has failed. If you’d like, a certified Your Mechanic Technician can come to your location to verify what type of failure the transmission has. Please look at this web site for more information and service options.
transmission inspection

Car shifts hard and rpms rev high on there own or car doesn’t shift at all, ABS and traction control lights are on also. 2005 Chevrolet Cobalt
ANSWER : Hi there – first task is to be sure the transmission fluid is at the proper level, and in good condition (more pink than black, and no burned smell). Low fluid, or dirty fluid, can cause lots of unexpected transmission behavior. The second task is to check for problem codes, whether the Check Engine light is illuminated or not. The possible problem we’re looking for here is a failing throttle position sensor – which interacts with the transmission controller and affects shifting behavior. I recommend a transmission inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.

Battery and oil light come on when trying to start car, take keys out try again car starts no problem and lights go away
ANSWER : Of course, don’t switch gears without being fully stopped, unless your Owner’s Manual or the manufacturer has alternative advice. However, the gear shift issue has no relation to the no-start problem you are describing. Inasmuch as you only have 6,000 miles on the car, the "constant on and off" that you believe has occurred is meaningless in comparison to the expected total vehicle service life. That is, assume what you perceive as "constant on and off", during merely 6,000 miles, might be equivalent to using the car "normally" for three years. A new car should be trouble free for at least 5 years, unless there is a defect, so your "constant on and off" is not a causal factor for any fault on the vehicle. What you might have is a defect in the ignition switch, or perhaps the immobilizer system, but if the problem is not in the switch itself, clearly there is an electrical problem.

If your vehicle is under warranty, by law the dealer MUST repair the issue you are describing within a prescribed time frame and number of "attempts", otherwise the dealer will run afoul of Federal and state Lemon Laws that give you very specific rights, and recourse (contact an Attorney; we are Mechanics, NOT attorneys). Consequently, if the vehicle is still under warranty, to save yourself money do be sure to seek a resolution from the dealer. If the vehicle is not under warranty, obviously a certified Mechanic from YourMechanic could identify the electrical fault and resolve this for you. If you want to go that route, please simply request a no start diagnostic -electrical system and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

The starter off and on wont turn over when trying to crank the car.
ANSWER : Hello, thank you for writing in. Often when starters are installed they come with a shim. These shims need to be installed to help hold the starter at the proper angle. If the angle is off the gears may not mesh correctly putting excess pressure on it that the starter cannot compete with. If the starter did not come with a shim, or you do not have it anymore, you can likely purchase or fabricate one relatively easily. If this does not solve the issue, make sure there are no wires that are being pinched or shorted out when the full weight of the car is being supported. For more help diagnosing the issue, contact our service department to schedule an appointment. And thank you for you service to our country.

Car in park shifter will move through gears but wont shift through the gears its stuck in neutral have emergency brake on so it wont roll
ANSWER : From what you’ve described, it sounds like the shifter cable came off at the transmission or the shifter. I’d suggest checking the shift linkage on the transmission to see if the cable came off. This is due to the connector end bushing falling apart and not being able to hold the cable on any longer. Some cables have to be replaced as a whole and as with others the bushing can be replaced to fix the cable. I’d suggest contacting a certified technician, such as one from YourMechanic, who can come diagnose your shifting issue and make the necessary repairs to your vehicle. Good luck.
