my car is hesitant to accelerate when changing down to second gear uphill and sometimes it just won’t accelerate.
My car just won't accelerate when going uphill, sometimes changing down to the second gear it still hesitate to accelerate. There's no engine light or what's so ever on the dash, I've changed the clutch kit on Thursday the 19th Jan 2017, and cleaned the TPS & MAF Sensor. The Fuel Pump was changed together with the it's filter and the O2 Sensor is also new. The last suspects are the injectors. I've literally changed all my sensor and also installed the new catalytic converter. I'm starting to worry that by the time I found out what the culprit is, I would have ch
Experienced mechanics share their insights in answering this question :
Hi there. What were the diagnostic results? What were the data readings from the ECM? What diagnostic process did you use to determine the other parts were in need of replacement? These are the questions that I ask anytime I am presented with a unique concern such as this one. Compare data reading to factory specs before replacing any parts; air flow meters can be presenting incorrect readings that are not considered faulty readings. The ECM will simply adjust fuel trim to compensate. Of course, the meter may not be changing the reading at all from idle; imagine how the ECM will react to increased throttle opening with an airflow reading that matches idle speed (lots of throttle and no air) or increased airflow without an increase in throttle position if the TPS is faulty (lots of air and no throttle). I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a car has low power inspection.
How to Identify and Fix Common car Problems ?

An engine that is hesitating to accelerate is most likely dealing with a fuel/air mixture that is too lean. Engine`s that are running inefficiently will begin to show signs like hesitation which will only become worse over time.
Clogged Fuel Filter: The job of the fuel filter is to filter out containments in the fuel and if it becomes clogged it can restrict the amount of fuel that reaches the injectors. This can cause a vehicle to accelerate slowly. Fuel filters are designed to be replaced on a regular basis.
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.
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.
Why does my Toyota hesitate when I accelerate? Toyota hesitates when you accelerate because of the electronic throttle control system. This can often be solved by installing a part called a Throttle Response Controller.
Wondering why your car feels sluggish when accelerating? It could be due to a dirty air filter, a bad spark plug, or a faulty catalytic converter — among several potential suspects behind sluggish acceleration.
If you press or let up on the pedal, there will be a delay before the engine responds. This is because of the time it takes the throttle motor to activate the throttle opening. Throttle response should be nearly immediate and not delayed. Gas pedal delay is a safety defect because it can cause accidents in emergencies.
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.
When a throttle body is not functioning correctly, you`ll usually notice a distinctly poor or very low idle. If the problem is really severe, you might even begin stalling when coming to a stop or when the throttle is quickly pressed.
If your car hesitates when accelerating at low speed, you likely have a lean air-to-fuel mixture—meaning the gas getting to your engine doesn`t have the correct mix of fuel and air.
Hesitation is when your engine misfires, stumbles or lacks power when you accelerate or step on the throttle. The problem often means the air/fuel mixture is not being properly enriched or is going lean, or the ignition system is weak and is misfiring when the engine comes under load or the air/fuel mixture goes lean.
An engine that is hesitating to accelerate is most likely dealing with a fuel/air mixture that is too lean. Engine`s that are running inefficiently will begin to show signs like hesitation which will only become worse over time.
The sudden acceleration phenomenon and recall by Toyota affect the following models and years: Toyota Avalon (2005-2010) Toyota Camry (2007-2010) Toyota Prius (2004-2009)
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.
Rough Shifting or Jerking Transmission
Causes of rough shifting include: Transmission Fluid Low or Poor Condition – Vehicles low on transmission fluid or that are operating with worn out or contaminated fluid are likely to experience hard shift conditions.
If you notice your car making a grinding sound when it accelerates, your issue is likely to do with your transmission, a problem with your differential, a bad wheel bearing, a damaged CV joint, or a worn engine/motor mount.
In most cases, you`ll see a noticeable difference in performance after replacing your spark plugs and wires. The engine will run smoother and faster, and the car will have better acceleration.
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.
Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.
A sputtering engine may just mean you need to have your fuel filter replaced. All vehicles have a series of vacuum hoses that create the fuel pressure. If one of them leaks or is damaged in any way, you will lose significant fuel pressure. The vehicle`s exhaust system can greatly impact the engine`s performance.
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.
Transmission Hesitation
This warning sign feels less like a stumble or a stutter during shifting, and more like an annoying pause before the next gear engages. If your automatic transmission starts hesitating between gears, it`s going to feel like something is off. You`ll want to have a mechanic examine the system.

Car won’t start. The check engine light, battery light, and oil change light are coming on. I tried jumping the car and nothing happened. Why won’t my car start?
ANSWER : Hi and thanks for contacting Your Mechanic. If sometimes your vehicle will start with the new alternator and sometimes it won’t, then there is a loose connection in your charging system. Check all of the wires to the alternator and to the battery. Make sure that the battery cables are clean and tight. Make sure that the wires to the starter are clean and tight. A loose ground to the ignition system will cause the vehicle to not crank over. Check all of the ground wires from the battery to the starter. Make sure that they are clean and tight. If you need further assistance troubleshooting your no start situation, then seek out a technician, such as one from Your Mechanic, that can assist you.
I was driving had my car on gear and lost acceleration. I pushed the clutch in and put on gear but only grind but won’t move?
ANSWER : If the clutch lever, on the transmission, is functioning something has mechanically failed in the clutch and/or the transmission. If the clutch failed, and you heard gears grinding, as you tried to shift the transmission, some damage may have been done to the transmission. Even if just the clutch has failed, the engine and transmission will have to be separated to find the cause of the failure and worn out or broken parts will likely have to be replaced . To request an inspection, the recommended service is clutch system diagnostic. If you request that diagnostic, the responding certified mechanic will evaluate what you have and let you know of your repair options and costs. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
car hesitation in 1st and 2nd gears , its totally fine in higher gears . hesitation means light jerks , what’s the issue?
ANSWER : Hi there. You may be having an engine misfire since it is only when you are accelerating. The misfire may be due to worn spark plugs or the ignition system coil failing. The ignition system includes the spark plugs, wires, and coils which need to be checked for signs of failure. I recommend having the engine completely diagnosed and scanned for codes to see what is causing the misfire in the engine. You may only need a tuneup or may need more ignition components. I recommend having a technician, such as one from YourMechanic, inspect for trouble codes and replace any failing components.
Car sometimes won’t accelerate but it will rev
ANSWER : Hi there:
The symptoms you’re describing can be caused by multiple issues within the vehicle’s driveline including; transmission, transmission linkage, or the front transaxle. In some instances, it’s an indication of low transmission fluid or damage to hydraulic lines that power the transmission; while in other instances it can be a bad sensor or damage to the flywheel. The best way to eliminate the guesswork is to contact one of our local mechanics and have them test drive your Ford and complete a vehicle is vibrating inspection. When a good mechanic test drives a vehicle, it makes diagnosing the problem much easier.
Car won’t change gears when I stop and try to put car in Park. It won’t go until I remove the key.
ANSWER : Hi there. Check the shifter lock solenoid in the shifter housing. The lock solenoid may have an issue as the ignition key is on. I recommend replacing the shifter lock solenoid. Also, I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your lock solenoid in your shifter if your vehicle still continues to not going in into park after replacing the shifter lock solenoid.
My manual car won’t go into gear, it turns on and the clutch goes down perfectly fine. It happened after my gears grinded, the car
ANSWER : If the clutch mechanism is releasing properly, and the shift linkage is not malfunctioning, your transmission will have to be removed from the vehicle and inspected. Once a transmission has been removed from a vehicle, if the problem is a broken or worn part or parts, and the transmission has 100,000 miles or more, the most cost effective approach is to just simply rebuild the whole transmission. There are transmission rebuild kits that are sold just for this purpose. Rebuilding a transmission is no big deal and is indeed easier in many respects than rebuilding an engine. You can rebuild your transmission right in your own garage. You can NOT rebuild an engine in your own garage due to the highly specialized, and extremely costly, machine shop equipment required. Occasionally, mobile mechanics will take on a transmission rebuild job especially as once the mechanic removes the transmission from the vehicle, it is just simply a modular unit that can be easily transported to a mechanic’s shop and rebuilt right there and then returned to your vehicle. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
Car starts, gears change, car won’t go.
ANSWER : Hello, thanks for writing in. From what you describe, it would appear that your vehicle may be having transmission issues. The symptoms you are experiencing can be caused by a wide variety of things. A few common causes are a bad shift solenoid, a bad transmission valve body, or a faulty torque converter. As the possibilities could be many, I would recommend having a transmission specialist look at the vehicle for the best diagnosis.
