Experienced mechanics share their insights in answering this question :
Hello. If the symptoms began after using adding fuel it may be possible that you are experiencing problems due to a low quality batch of fuel. There are instances where a low quality mixture in the fuel results in poor performance from the engine. Low quality fuel can cause the engine to experience misfires, and in more serious cases engine knock or ping. If you believe that the issue may be related to the fuel, draining and refilling the tank may be the best way to correct the issue. Depending on how much fuel was added, you may also be able to add fresh fuel to the tank to dilute the mixture. Also keep in mind that similar symptoms can also be caused by other issues with the engine management system, though in most cases those issues would set off the check engine light.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
There are a few reasons why your car might be struggling to accelerate. It could be due to a problem with the timing belt, the spark plugs, or the fuel injectors. It could also be because you have a dirty air filter or a clogged fuel filter. The fuel system may also be low on fuel.
One of the most common reasons for poor acceleration is a problem with your car`s air intake system. If there is something blocking the air flow into your engine, it will prevent your car from getting the oxygen it needs to create the combustion needed for acceleration.
The most common cause of this problem is a faulty torque converter. Other possible causes include a dirty or faulty transmission filter, low transmission fluid levels, or a problem with the transmission control module.
Dirty fuel injectors may cause the engine to run lean which will in turn, cause hesitation when accelerating.
Recommended Services. Either you have a blocked exhaust like a bad converter, a muffler clogged from a broken up converter, or you have a bad ignition module or fuel pressure problem. First try replacing the fuel filter to see if it is clogged. Check to see if the fuel pressure is at 40 psi.
“Limp Mode” – If your car won`t accelerate over 25 or 40 mph, it could have engaged `limp mode. ` It is also known as a limp home mode, and it acts as a preservation feature. It is meant to get you home, to an auto mechanic, or safely off the road without destroying your engine.
A loss of power is most apparent when you`re accelerating, and can be due to a number of reasons including air flow into the engine, fuel flow and even faults with the exhaust system.
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.
There are several reasons why your Honda may hesitate during acceleration. The most common reason is a problem with the fuel system, such as a clogged fuel filter or faulty fuel injectors. Another possibility is an issue with the ignition system, such as spark plugs that need to be replaced.
If your car is not accelerating, the first thing to check is the air filter. The air provided to the engine for the combustion process passes through an air filter, which catches all the impurities and debris present in the air. With continuous usage, the air filter gets clogged and doesn`t let air pass through it.
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.
If your speedometer stopped working and stays at 0 MPH, you should have your car checked ASAP. The most common causes of a speedometer that stopped working include are a faulty speed sensor, a broken gear on the speedometer, damaged wiring, or a faulty engine control unit.
Most of the time this is triggered due to a problem within the transmission. Either minor like low or leaking transmission fluid, a loose or malfunctioning sensor or a major component problem.
If you are driving at 120 mph, it is possible that your vehicle is hitting the speed governer. This speed governer will prevent the vehicle from going past a certain speed by limiting engine power and reducing rpms.
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.
The reason it will not go over 2500 rpm is because the computer is in limp mode. This mode is for when the computer has a failure in it. Limp mode will trigger if there is an issue with one of the vehicle`s systems that the manufacturer suspects would cause major problems.
If your vehicle won`t go over 2K RPM (assuming it did prior to the issue), then your motor is most likely in limp mode. Limp mode is a feature of modern cars which severely reduces performance in order to do two things: 1) Allow you to drive the car to a safe location. 2) Protect further damage to the motor.
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.
Worn Transmission Fluid (Automatic Transmission)
Over time, the transmission fluid gathers dirt and grime. This can cause the engine to run roughly, stall or fail to accelerate when you press down on the gas pedal. You may need to have a transmission fluid change before more damage is done.
The best years of the Honda Odyssey are: 2015-2018, 2012-2013, 2009-2010, and 2004. The years you should absolutely avoid are: 2001-2003, 2005-2008, 2011, and 2014. Most issues are related to hiccups in first-year production of new powertrains.
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 your car jerks, stumbles or stutters while driving, it usually means something is interfering with the proper distribution and transfer of power from your transmission. Another example is if you`re driving a manual transmission and haven`t gained the feel of shifting for your particular vehicle.
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.

Van started acting up 2 days ago it wont go pass 20mph but it comes and goes? Any idea what it can be? No check engine light
ANSWER : Hello. If the symptoms began after using adding fuel it may be possible that you are experiencing problems due to a low quality batch of fuel. There are instances where a low quality mixture in the fuel results in poor performance from the engine. Low quality fuel can cause the engine to experience misfires, and in more serious cases engine knock or ping.

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.
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.
Engine Light and AT light. Car goes into limp mode
ANSWER : Hello. Most of the time this is the result of a transmission failure. It is common for this transmission to have internal pressure problem which will cause these codes. It can also be a voltage problem so I always check that first. I check the voltage going to the transmission and if it is too low I repair that issue which is commonly the ignition switch. If the voltage is fine, then the transmission pressures need to be checked and it will more than likely need to be replaced. I would have a transmission specialist look into this.
Car goes into limp mode when the check engine light and VSA light comes on
ANSWER : The lights that you have on and the vehicle going into fail safe mode is an indication you have a major system failure that will require computer to be tested for codes first. There are many possible codes it can be so the additional testing will be needed to isolate the cause of the problem.
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.
Traction light/reduced engine power and check engine light coming on
ANSWER : Hello. From what you describe, it would appear that your vehicle may be experiencing some sort of intermittent wiring or sensor issue. If the problem occurred again after driving over a bump, then it may be possible that a damaged or loose wire is shorting or having contact issues. A common issue that can cause stalling is a faulty crank position sensor or wiring. I would carefully examine the engine for any loose or damaged wires. If the Check Engine Light comes back on, I would recommend having the trouble codes scanned before resetting the computer.
Honda Civic 2008. AC stopped working suddenly and engine check light came ON for a day.Next day AC worked and no engine light.
ANSWER : Hi there. In both cases, when an AC system is not working and a warning light is coming on the dashboard, typically a professional mechanic will complete the same initial inspection, which is to download the stored error codes that triggered the warning light initially. This tends to give them an idea as to what is causing the problems. This could be something as simple as an electrical relay that is faulty or loose or an indication of a computer related "glitch". Either way, the best way to move forward is to have a professional mobile mechanic complete a check engine light inspection.
