Car jerks and signs of overheating
I have a 2001 Honda Civic Manual.
The car jerks when changing gears and show that it's overheating even though it's not. Once I push the gas a little and let go the arrow on the thermostat goes down immediately. This has me confuse and I would like to know what it can be. The mechanic wouldn't look at it because the check engine light does not light up.Please help!!

Hi There,
It does sound like your car may be overheating and that you may possibly have a bit of a cylinder head gasket leak. A blown head gasket may cause a number of different symptoms. A head gasket that fails between cylinders will generally cause a misfire and potentially compression leaks from one cylinder into another. Low compression will eventually result in a rough idling engine. When the head gasket fails between a cylinder and the coolant port, coolant may leak into the cylinder causing it to be burnt with the fuel charge in the combustion chamber. This often results in misfires on startup, especially after the engine is run, turned off and restarted and in some cases may result in the engine not maintaining enough cylinder compression to even run or start. This type of failure may not always show with a compression test. I would recommend having an expert from YourMechanic come to your location to properly diagnose the symptoms you describe.

How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
The most common causes of overheating include low coolant level (including that due to leaks), a faulty thermostat, a plugged radiator, a faulty radiator pressure cap, collapsed hoses, non functioning cooling fans, and a faulty water pump or drive belt.
Dirty fuel injectors are among the most common reasons for why an accelerator becomes jerky. The dirty injector leads to your car losing power when you attempt to accelerate while at a stop and when you try to drive at a consistent speed. This is the result of an engine misfire.
The most common reasons a Honda Civic is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat. Coolant leak (water pump, radiator, hose etc.)
There are several symptoms that can indicate your Honda engine is overheating, including: Temperature gauge reading high One of the most obvious signs of engine overheating is a high temperature reading on the temperature gauge. If the gauge is in the red zone, it`s likely that your engine is overheating.
RPM fluctuation is a common issue for cars with faulty spark plugs as they fire the fuel with the pistons. If they wear out, your acceleration slows, and jerking and misfire start occurring, which, in combination, causes poor fuel economy and vibrations.
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.
A Transmission Fault
Shifting issues can sometimes cause your vehicle to feel like it is jerking when accelerating. If you have internal transmission damage, it can cause the gears to slip [and] engage over and over again, which feels like jerking when accelerating.
Overheating can be caused by a: Cooling system leak – This is the most common cause for a car to overheat. The radiator, hoses, water pump, head gasket, and thermostat housing are all components of the cooling system, and all can be susceptible to leaks.
A few different things can cause all of these symptoms. The most likely would be a failing fuel pump, bad spark plugs and wires, a MAF sensor issue, vacuum leak, or a faulty oxygen sensor.
The lack of acceleration could be caused from the vehicle actually overheating which could have lead to serious engine damage. A proper cooling system diagnostic should be performed by a qualified technician.

My heat in my car stopped working two days ago and now my car is overheating. I put antifreeze in my car and it’s still overheating 2006 Pontiac Grand Prix
ANSWER : Hi there – you may have 2 related events here, a coolant leak, and a problem with the heater system. The current issue may be air inside the cooling system, which can cause overheating, and a lack of heater function. The lack of heater function could have 5 causes: the engine is not getting up to correct temperature (center of the gauge) due to a malfunctioning thermostat, the heater control valve is not letting hot coolant into the heater core, there is a restriction in the heater system that is preventing adequate hot coolant flow through the heater core, the heater fan is not working to transfer heat from the heater core to warm air for the passenger compartment, or the air blend doors inside the heater are not working properly to route warm air to the desired vents. I would recommend a heater system inspection](https://www.yourmechanic.com/services/heater-is-not-working-inspection) by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

car is overheating and leaking water and anti freeze
ANSWER : Coolant leaks can occur because of cracked hoses, leaking gaskets, faulty water pumps, or damaged radiators. When the coolant level goes low, the engine will start to overheat due to the low coolant level. I would first recommend giving the cooling system a visual look over. If it is not obvious where the coolant leak is coming from, I would recommed having the cooling system pressure tested in order to determine the leak source. If you would like to have your cooling system pressure testedcoolant is leaking inspection, consider YourMechanic, as a certified technician can come to your home or office to inspect your cooling system.

I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you

My car overheated while on the highway. I added coolant and let the engine rest and cool down. Now the car will not start. How can
ANSWER : Hi there:
Unfortunately, there is no exact reason we can offer to you as to why the vehicle won’t start now after your overheating issue; without first inspecting the vehicle. However, if the vehicle overheated on the highway there is a high possibility that major engine damage has occurred, which is possibly why the vehicle won’t start now. This damage could include head gaskets being blown, which can cause coolant to enter the internal portions of the engine and lead to additional damage. The best thing for you to do is have your vehicle towed back home, then contact YourMechanic.com to have one of our professional mechanics complete a car is overheating inspection.

Hi, i was driving my car just fine today when all of a sudden it started jerking. it jerked a lot getting up to about 20mph then i
ANSWER : Hi there. I wouldn’t suspect that removing the battery has caused any problems. When your engine runs rough, it can be caused by multiple issues, ranging from a vacuum leak to fuel system component problems, and ignition system issues. I would recommend having one of our professional mobile mechanics come to your location and complete an engine is pulsating inspection. This will allow them to isolate the source of your issues and recommend the right repairs.

Replaced alternator on car 2 times each time shows it’s charging 14v let car run for a little bit then test drive and car voltage
ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.

I was stopped on the freeway, started to go about 5 mph, the car jerked and stop without warning like the wheels locked up.
ANSWER : Hi, thanks for writing in. I’d be happy to try to help. It is hard to definitively diagnose what the issue is. At first it seems like a transmission issue. Automatic transmissions are rather complicated and can do strange things when they malfunction. If not an issue with the transmission, you could also have a clutch issue. Always start by checking the simple components first. Check your transmission fluid level. Make sure your transmission filter is clean and debris free. When you have the transmission pan off, you can look and see if there are any metal shavings at the bottom. There is often a small magnet at the bottom of the pan designed to gather any metal shavings for a quick diagnosis. This is a sign of more serious transmission problems. Unless you have experience with automatic transmissions, it is not recommended that major repairs be done at home. I suggest taking your car to a transmission specialist for help.

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.
