I do not know if my battery or cables are bad.

I have been having problems starting my car, not to where it doesn't start but having trouble. I just cleaned both of the cables and screws and bolts. I noticed only the positive or red one was corroded not the negative or green. I plugged everything back up screwed everything back in tight as possible and its still having problems starting up. Not as bad but definitely some hesitation too start. The battery is not new but far from old and the cables look a little old but not enough for a problem.

My car has 132000 miles.

Experienced mechanics share their insights in answering this question :
Hello, thanks for writing in. It is possible that the cables are bad internally. Over time they will form corrosion inside of them that will cause this. Most of the time the problem is the battery though. I typically have the battery load tested first. If it fails then the battery needs to be replaced. If it is fine then I do a voltage drop test of the cables as the problem may be the cables or the starter. I always double check the oil too because low oil can affect how well the engine cranks over. If you would like help having this looked at, consider having an expert automotive technician from YourMechanic come to your home or office to inspect and diagnose this issue for you, and make or suggest any repairs as needed.

How to Identify and Fix Common car Problems ?

Fuel injectors may become dirty over time and not be able to provide as much fuel to the cylinder as is needed. Dirty fuel injectors may cause the engine to run lean which will in turn, cause hesitation when accelerating.
One of the main causes of poor acceleration in a Honda Accord is dirty transmission fluid. If the fluid is old and hasn`t been changed in a while, it can cause all sorts of problems with the car`s ability to shift gears properly.
Fuel injector nozzles can become clogged over time, which can lead to a sputtering engine, slow acceleration and the car not having enough power. Fuel injectors can be cleaned if the problem is caught early, but as the conditions worsens, the injectors may have to be replaced.
The most common causes for slow acceleration in Honda Accord are clogged air filter, dirty mass air flow sensor (MAF), clogged fuel filter, fuel pump malfunction, faulty oxygen sensor, dirty throttle body, worn spark plugs and clogged catalytic converter.
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.
Symptoms. Rough starts, hesitation and poor acceleration are all common symptoms of a bad spark plug. If a spark plug or multiple spark plugs are faulty, they will have trouble creating the spark that causes the ignition process in your vehicle.
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.
One of the most common causes of jerky acceleration is a dirty fuel injector. Your fuel injectors are responsible for pushing fuel into your engine`s cylinders. This means they control the timing and amount of fuel used to keep your engine running.
A sputtering engine is a sign of a lean fuel mixture in the combustion chamber. This can happen if you have a clogged somewhere in the fuel system that impedes the delivery of fuel into the chamber. For example, your fuel filter or fuel lines might be clogged.
Why does my car not accelerate when I push the gas? A car not accelerating properly can be caused by a number of things. It could be due to the throttle body, gas tank, spark plugs, or the ECU. It could also be because you have a dirty air filter or a clogged fuel filter.
SUA happens when an electronic malfunction occurs inside of the vehicle, causing the throttle to expand and the vehicle to accelerate without the driver`s intervention. Aside from unexpected acceleration, SUA can also prevent drivers from braking or returning the vehicle to idle if it is in gear.
Many supposed carburetor-related problems like low-speed hesitation can be traced to improper ignition timing.
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.
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.
Engine Hesitation

An engine that hesitates, or stumbles, upon acceleration is often the result of incorrectly gapped spark plugs. If spark plugs are gapped too wide, the ignition spark loses some of its strength as it crosses the spark plug gaps. This can result in engine hesitation.

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 few reasons your car may shake when accelerating but not coasting. The most common reason is that the engine is misfiring. When the engine misfires, it doesn`t run as smoothly as it should and can cause the car to shake. Another possible reason is that the spark plugs or ignition coils are dirty or damaged.
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 catalytic converter is part of the exhaust system, and it is tasked with changing carbon monoxide into carbon dioxide before it is released through the tailpipe. If the catalytic converter gets clogged, exhaust may back up into the engine, and this will make the engine sputter.
This is a common symptom of a plug or wire electrical current problem. Air or Vacuum Hose – Another common cause for engine vibration and power loss is when air or vacuum hoses come loose, begin to leak, or rupture. The three necessities for all combustion engines are air, fuel, and spark.
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 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.
(1) An accelerometer is an electromechanical sensor that measures static and/or dynamic acceleration forces acting upon an object by measuring the acceleration (the rate of change of velocity) along one, two, or three axes.

Hooked up battery cables to wrong car when jumping it
ANSWER : You may have damaged the car you were jumping from. I have seen alternator, ECM, various relays, and fuses damaged from improper jumping. You should monitor the problem to see if it continues to get worse. If so, have a local expert inspect the clicking noise and pinpoint any appropriate repairs that should be made.

My battery cables are to short to reach the battery can I just add some wire or do I have to replace the whole thing
ANSWER : Hello. I would recommend purchasing and installing the correct length cables to avoid any potential connection issues when adding additional battery cable wire. As you may know, there are different thicknesses of electrical wire required for different loads of electricity to pass through them. Additionally, any time there is wire spliced together like this, you run the risk of connectivity issues. I would recommend purchasing the correct length cables to install.

Bad battery cables or terminals?
ANSWER : Your car not starting may be a result of many possibilities, however you are on the right track. First try checking the terminals to be sure they are not corroded, dirty or have a poor connection. Also, check the cables to be sure they are free from breaks in them or exposed wire. If this all checks out, you may have a weak or dead battery. There are a few reasons why this may also be the case such as a bad grounding problem or a failing alternator. I would suggest having an expert from YourMechanic come to your location to take a look at your car to properly diagnose your starting problem.

Sluggish start. Bad starter or bad battery? Female. Don’t want to get taken by shop.
ANSWER : Hi! That "sluggish starting" (slow cranking speed) is the most common symptom when a battery is at the end of its life. The age of your car is also just about in the normal range for how long batteries last. You are correct that it is very unlikely to be a failing starter. Here’s the good news: many automotive service businesses will test a battery for free (or close to it); it’s one of the least costly things to have wrong with your vehicle; it didn’t leave you stranded. I suggest having it tested today! If you’re trying to avoid having your car in a shop, consider YourMechanic, as a certified technician can come service your battery at your home or office to fix this issue.

I thought I had a bad starter turns out that it was a bad battery I installed a new battery and I could not turn the lights off,
ANSWER : Hello. If the lights are staying on then you more than likely have a bad combination switch. The switch fails internally and causes this. It can also be a relay that is staying on, but that is not as common. I would typically use a voltage meter to test the circuits to make sure that the switch is bad. If you are planning on having this fixed, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose this.

Replaced my battery and replaced ends to the battery cables – does not want to start until I turn it over a few times – I think it my main cable.

My negative battery cable start smoking when the car is running.
ANSWER : There is a faulty, high resistance (often due to corrosion, wire defect or break or loose mechanical connection) connection at the battery post and/or at the vehicle ground(s) at the frame. The recommended and safest practice is to replace the cable (cables can corrode within and cable crimps at the cable ends can’t be serviced without shortening the cable). When replacing, particular attention should be paid to the cleanliness and quality of the vehicle ground connection. This is a safety issue and consequently the repair is recommended at your earliest convenience. If you desire mobile service on this repair, the service to request is battery cable replacement and the responding certified mechanic will deal with it promptly.
