Experienced mechanics share their insights in answering this question :
This may be a sign of a failing throttle position sensor. The throttle position sensor (TPS) is a sensor used to monitor the throttle position of the throttle plate inside the throttle body in relation to your foot position on the gas pedal. Based upon the inputs from the sensor reading your foot’s position on the pedal, the ECU then makes the direction to supply more or less fuel to the motor. When this sensor is not working properly, this can cause intermittent responses when pressing the gas pedal as you describe. To avoid any unnecessary repairs, I would suggest having a professional from YourMechanic come to your home to diagnose your Check Engine Light and service your throttle control system as necessary.
How to Identify and Fix Common car Problems ?

Usually, when the check engine light is on and the car is shaking, that means you`re dealing with an engine misfire. Basically, the check engine light comes on whenever there`s an issue that could increase vehicle tailpipe emissions.
This happens because of clogged injectors, dirty fuel filters, or a defective fuel pump. The fuel delivery system comprises many parts that deliver fuel to the engine. If one of these parts is not functioning correctly, it can trigger the check engine light to flash. The engine chomps more fuel whenever you accelerate.
You may need to have a mechanic check the oxygen sensor, the mass airflow sensor, or both. The oxygen sensor will likely need to be replaced if it is dirty, while the mass airflow sensor can simply be cleaned. A dirty sensor may prompt the “Check Engine” light to come on in the car.
The source of the problem could be from tires that are not balanced or a worn-out spark plug. It could also be loose lug nuts. A car also vibrates for a number of reasons when you accelerate. Typically it`s from a damaged inner CV joint.
The most prevalent cause of vibration is problems with your wheels or tires. The potential problems include improper wheel and tire balance, uneven tire wear, separated tire tread, out of round tires, damaged wheels and even loose lug nuts.
There are several reasons the check engine light may be triggered: A loose, cracked, or faulty gas cap can cause fuel to evaporate, thus causing your check engine light. Make sure your gas cap is tight. If that is the problem, the check engine light should go off within 10 or 20 miles after you start driving again.
A malfunctioning TPS will cause your engine to run poorly. Generally the engine will idle fine but will have difficulty accelerating.
The accelerator pedal sensor transmits the position of the accelerator pedal to the engine control unit. Based on this information, the load requested by the driver can be implemented immediately.
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.
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.
The most common reasons for a shaky car include: Lack of fuel – running low on gas or there is an issue with your fuel injectors or fuel system. No spark – need to replace your spark plugs.
Poor Quality Fuel
A major reason of vibrations in a vehicle is poor quality of fuel. Poor quality fuel usually has low levels of octane, because of a lack in octane, the engine tends to experience more load.

Car started to slow down and then the check engine light, battery, and engine oil light came on. What could cause this?
ANSWER : Hi there. It is possible that the battery cable came loose or the wires to the oil pressure sensor has came loose or failed. Check the battery cables and make sure that the terminals are tight and clean. Check the wires to the oil pressure sensor and make sure that they are connected and not broken. If everything looks good, then the oil pressure sensor may have failed. Plus, check the computer for codes and see what is stored. This will lead you to the part that could have failed. I recommend replacing the oil pressure sensor then checking to see if the lights will go out. If you need further assistance troubleshooting your vehicle, then seek out a technician, such as one from Your Mechanic, that can assist you with the warning lights that came on.
Gas cap notification and check engine light came on after getting gas. Car started to sputter and stall out.
ANSWER : Hi there. When the fuel cap is not securely fastened to the tank, it can create vacuum issues inside the tank; which triggers the error code to be stored in the ECU. The error will then trigger the check engine light until that code is reset by a professional digital scanner. If you’re still having sputtering or stalling issues, you should contact a professional mechanic to complete an engine sputtering inspection. This will allow them to diagnose what’s causing this problem and reset any error codes to hopefully correct the issue your Chrysler 300 is experiencing.
Was driving on the expressway and my car started shaking, check engine light turned on, oil light turned on and off
ANSWER : Hello, thank you for writing in. Shaking and vibrating typically comes from a misfire, or poor engine performance. A lack of oil will absolutely contribute to these symptoms and amplify them, if not cause them to begin with. You want to turn your attention to the cause of the oil leak. If external (you can see the leaking oil), then you will want to trace the leak to the component which has failed. If the leak is internal (or the engine is consuming oil), the leak will be harder to find. It will also explain the poor engine performance due to excess oil in the combustion chamber. A head gasket is one of the main components that will fail and cause these issues. It is however not common for a vehicle this age to have these kinds of problems. You will also want to scan the computer, and see what codes are triggering your check engine light. These diagnostic tools will help you determine what system(s) is to blame for the malfunction.

Battery light goes on when I start car then turns off, if I rev engine light comes back until rpms go down. Abs goes comes on/off
ANSWER : Batteries can die due to faults in the charging system so ideally a suspected "faulty" battery should be load tested before a decision is made to condemn it. The only exception to this rule is if the battery is already clearly "old" (greater than 5 years) but even then once you put a new battery in, as a replacement for a "dead" battery, you have to comprehensively check out the charging system. Diagnostic Trouble Code P0460 will result in disruption of the dashboard fuel gauge’s ability to accurately report your tank’s fuel levels. The fuel gauge readings may be erratic, or read somewhere off scale. Vehicles equipped with a low fuel warning light feature may also suffer from erratic low fuel warnings in the event of a code P0460. Unless the P0460 code has been reported alongside other trouble code, all of the vehicle’s essential systems should otherwise function normally. I would recommend that you request a check engine light diagnostic to first resolve the fault causing the P0460 code to set. The check gas cap light warning light could be due a faulty gas cap and/or small leaks in the EVAP system.
P2196 OBD-II Trouble Code. came and went in 24 hours. 4 starts.
ANSWER : If the mechanic tested the output (functioning) of the oxygen sensor, especially according to the protocol at this link and found that the sensor was non functioning at that time, what you might be experiencing is a "failing" oxygen sensor and so the latest instance of Code P2196 might be explained by that. A complexity though is Code P2196 has many causes other than a failing oxygen sensor including: a faulty fuel pressure regulator; MAF (Mass Air Flow) sensor; ECT(Engine Coolant Temperature) sensor or damaged ECT wiring; leaking or stuck open fuel injector or injectors; and spark plugs and/or coil pack. Basically, if the Code (P2196) recurs, the oxygen sensor output can be re-tested but the mechanic will hopefully be aware of all these other possible causes of that Code setting. If the Code recurs, you can request a check engine light diagnostic and a certified Mechanic, dispatched by YourMechanic right to your location, will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
Check Engine Light comes on after starting pickup
ANSWER : Hello there, thank you for asking about your 1992 Isuzu Pickup. A professional will have the correct equipment to read OBD1 codes. Retrieving the diagnostic trouble code(s) is the first place to start when diagnosing your vehicle. Increasing RPMs changes engine load, which can in turn affect many different sensors and components, causing the Check Engine Light to illuminate. The only way to narrow down the options and find the culprit is through in person diagnosis with an OEM compatible scan tool. A certified technician from YourMechanic can retrieve the OBD codes at your home or office.
Car shaking when it goes above 45-60mph and stays in that condition with check engine light flashes
ANSWER : Hello, and thank you for writing in. The vehicle may be having one of many issues. Shaking is usually caused by some kind of imbalance with the engine and its combustion cycles. This may be a problem with the fuel or engine, or it may be a problem with the electronics and how they are regulating the engine. At this point, with the symptoms you are having, it is going to be a guessing game. You can start by having the vehicle scanned for diagnostic codes. When the check engine light comes on, there is some kind of error being detected, and you can use these error codes (known as diagnostic codes) to help point you in the right direction. Due to the high RPMs, it sounds as if the transmission is not wanting to shift. There may be an issue with the speed engine and transmission speed sensors. You may also want to look at the bottom of the vehicle and think about any of the sensors that may have been affected by the chemical spray.
