Rough idle can be caused by
dirty fuel injectors, incorrect idle speed, exhaust restrictions, vacuum leaks, incorrectly installed or damaged spark plugs, a defective or clogged fuel pump or fuel filter, failing electrical components such as the ignition control module,...
There are a number of things that may cause the car to hesitate (https://www.yourmechanic.com/services/engine-hesitates-during-acceleration-inspection) when accelerating such as low fuel pressure, a dirty or faulty mass air flow sensor, clogged or
dirty fuel injectors, a faulty throttle position sensor or...
Among the possible causes of a rough idle are contaminated gasoline,

Rough idle could be due to a bad tank of gasoline,
dirty fuel injectors, incorrect idle speed, incorrect...
The poor operation that you are describing could be due to a bad tank of gasoline,
dirty fuel injectors, incorrect idle speed, exhaust restrictions, vacuum leaks, incorrectly installed or damaged spark plugs, a defective or clogged fuel pump or fuel...
Rough idle and excessive shaking of the engine could be due to a bad tank of gasoline,
dirty fuel injectors, incorrect idle speed, exhaust restrictions, vacuum leaks, incorrectly installed or damaged spark plugs, a defective or clogged fuel pump or fuel filter, failing electrical components such as the ignition control module, plug wires, coils, and spark plugs, a defective airflow sensor, dirty oxygen sensors and other causes.
Fuel related misfires can be caused by many different things such as low fuel pressure, faulty or
dirty fuel injectors, a faulty O2 sensor, a dirty or failing mass air - flow sensor, a faulty or dirty idle air control valve or a vacuum or intake leak.
There are many causes of hard starting but illustrative ones are a faulty engine coolant temperature switch (sensor), malfunctioning idle air control (IAC) valve, vacuum and EGR leaks, inadequate fuel delivery or pressure (clogged fuel filter,
dirty fuel injectors), and contaminated or old gasoline.
Usually when you have a problem like this, it's due to
dirty fuel injectors, throttle body, EGR valve or mass air flow sensor.
A rough idle (https://www.yourmechanic.com/services/car-idle-is-rough-inspection) may be caused by things such as low fuel pressure, low voltage to the fuel injectors,
dirty fuel injectors, a vacuum leak, a faulty...
There are many causes of hard starting but illustrative ones are a faulty engine coolant temperature switch (sensor), worn spark plugs, inadequate fuel delivery or pressure (e.g., clogged fuel filter),
dirty fuel injectors, contaminated or old gasoline, malfunctioning idle air control valve, poor engine compression, and so forth.
Hi There, There are a number of things that may cause the car to hesitate when accelerating such as low fuel pressure, a dirty or faulty mass air flow sensor, clogged or

Other causes of hard starting are a faulty engine coolant temperature switch (sensor), worn spark plugs, inadequate fuel delivery or pressure (e.g., clogged fuel filter),
dirty fuel injectors, contaminated or old gasoline, poor engine compression, and so forth.
It can also mean there is less fuel than usual such as a weak fuel pressure,
dirty fuel injectors, bad O2 giving computer a bad reading so fuel is lessened, bad engine coolant temperature sensor giving computer a hot reading so fuel is lessened.
Possible factors include poor compression (dirty piston rings, scored cylinders, dirty or worn valves),
dirty fuel injectors, dirty cooling system, dirty and partially clogged catalytic converter.
Dirty fuel injectors can create issues like stalling, hesitation, misfiring, lack of power, and poor fuel economy — all due to carbon buildup.

When the
injectors are
dirty, they do not atomize
fuel effectively.
Some of the components that could be
dirty or faulty include the
fuel injectors, the throttle body (https://www.yourmechanic.com/article/how-to-clean-a-throttle-body-by-timothy-charlet), or the EGR system.
However, other mechanical systems that are monitored can also contribute to the problem If the car is slow to accelerate and seems to stumble when you drive, that's more indicative of a
dirty mass air flow sensor or clogged
fuel injectors.
Beyond the MAF sensor, in most cases, an engine that stumbles when it's cold is caused by one of three different components: clogged
fuel injectors, a
dirty throttle body, or an EGR valve that is damaged or also...
Although changing the spark plugs and O2 sensor tend to fix this type of issue, it could also be caused by
dirty fuel filter, clogged
fuel injector lines, or another electrical gremlin.
This can happen for a variety of reasons ranging from low
fuel pressure to bad
injector pulse to even just a
dirty...
This could be the result of damaged mass air flow sensors, EGR valve, O2 sensors or simply due to
dirty throttle body or
fuel injectors.
Most of the time, this type of acceleration issue is caused by a
fuel restriction, either a damaged or worn out
fuel pump,
dirty fuel filters or clogged
fuel injectors.
