It's below zero, but I have a battery with high CCAs and it was warmed up to normal temp before I started driving. When accelerating on the freeway, the engine stutters and misses as if it's not getting a steady supply of air, fuel, or power. (I'm female with no mechanical ability, this is just a guess based on what it feels like.) When I tried to go from 50 to 70, the check engine light started blinking. I pulled over. I have about 1,000 miles left before my oil change is due. Temp gauge held steady. While in park, I revved it up to 3,000 RPM and held it there; no stuttering
You could have gotten some bad gas from a gas station that has a lot of water in the fuel. When there is excessive water in the fuel, the engine will tend to run rough at a low rpm and run smooth at a higher rpm. Since the check engine light was on, I suggest having the computer checked to see what codes maybe stored or pending to have a starting point of diagnostics. If you need further assistance with your engine idle being rough, then seek out a professional, such as one from Your Mechanic, to help you.
How to Identify and Fix Common car Problems ?

Any unusual shaking or vibrating forces coming from the engine is cause for concern. It could be something as simple as old spark plugs producing an uneven power delivery, it could be something serious like worn or broken engine mounts, or it could be even more serious in the case of internal engine damage.
There are a few reasons why your Dodge Journey might be lagging. It could be an issue with the spark plugs, the fuel injectors, the air filter, or the oxygen sensor. If you`re experiencing acceleration problems, it`s best to take your car to a mechanic so they can scan for trouble codes and diagnose the issue.
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.
Typically, the check engine light turning on (and is blinking/flashing), it indicates that your vehicle engine is misfiring. And this would explain why you`re getting sputtering as an additional symptom. Probably the most common reason for engine to sputter is lack of fuel.
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.
Loose or damaged engine mounts may also be to blame if your car shakes when accelerating. As previously mentioned, damaged and loose engine mounts can`t efficiently absorb the vibrations produced by your cranking engine, so you`re likely to feel them when you step on the gas.
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.
Worn out spark plugs are one of the most common causes of engine shaking. If your spark plugs are dirty or worn out they will be unable to fire properly and create the spark your engine needs to ignite the fuel. This causes your engine to misfire. Replacing your spark plugs is typically inexpensive.
The most common causes of misfires are worn, improperly installed, and mishandled spark plugs, malfunctioning ignition coils, carbon tracking, faulty spark plug wires and vacuum leaks.
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.
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 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 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.
Chugging or rattling noises
A chugging sound could mean there`s a blockage in the exhaust system. [2] A rattling sound might mean it`s out of alignment. A hissing sound could mean there`s a crack in the exhaust system. Take your car in for an exhaust system check.
Key Takeaway Rattling noises when accelerating can be caused by a number of issues, including damaged or worn-out suspension components, bad wheel bearings, low transmission fluid, loose heat shields, and faulty engine components.
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.
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.
This monitors the position of your foot on the pedal relative to how much fuel is introduced into the throttle body. When this is faulty, it can cause a jerking or hesitating effect as you describe.
Improperly functioning spark plugs cause an uneven burn of fuel in the engine, resulting in fluctuating RPMs and a louder noise. You might also experience increased vibrations of your vehicle while sitting idle or while traveling at low speeds. These vibrations originate from the engine and can shake the entire car.
In some cases, a misfire will cause your engine to run rough enough that you feel a noticeable shake. The check engine light will pop on, and it may even begin to flash.
Any unusual shaking or vibrating forces coming from the engine is cause for concern. It could be something as simple as old spark plugs producing an uneven power delivery, it could be something serious like worn or broken engine mounts, or it could be even more serious in the case of internal engine damage.
A clogged or failed exhaust gas recirculation or crankcase ventilation valve or faulty oxygen sensor can send the wrong signals to the computer and cause misfires.
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.
