Hello. You can try taking your car to a local auto parts store and have them plug into the scanner to see why the Check Engine Light is coming on. It may give you an idea if what is wrong, but may not give you a complete answer unless thoroughly scoped out. A fault code will give you an idea as to why the light comes on but doesn’t always give you a solid idea of the repair needed to solve your problems. Diagnosing why a vehicle is having symptoms often requires following a diagnostic tree. After getting information from the fault codes, there is a process of elimination that needs to be conducted. "Check ABC. If ABC checks ok, then check DEF. If DEF checks ok, then check GHI. If GHI does not check out ok, then replace XYZ." In your situation, since you are having multiple problems, I would insist on having an expert diagnose the vehicle, instead of blindly replacing components. This will ultimately save you time and money in the long run.
How to Identify and Fix Common car Problems ?

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.
The reduced engine power mode is usually indicated when there is an issue with the electronic throttle control system. The new problem may be connected to the old problem. General Motors put out a warranty extension on the accelerator. The pedal can break or fracture from excessive pressure being applied to the pedal.
Slow acceleration can be caused by a number of different things, including a problem with the oxygen sensor, the airflow meter, or the throttle position sensor. Your check engine light may also come on if there is a problem with the acceleration. Engine speed sensors may also be another factor.
The reasons for a check engine light turning on can range from something minor like a loose gas cap to something more serious like a faulty catalytic converter. It could even be a sign of internal engine failure. Ignoring the problem can turn a potentially quick fix into a costly and time-consuming repair.
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.
Clean or replace your vehicle`s air filter when your acceleration is acting sluggish. Put in new spark plugs when they go bad if your engine misfires and hesitates. Replace your vehicle`s fuel filter when there`s a delayed response when you accelerate.
Faulty Throttle Body: A throttle body is part of the of the air intake system which helps control the amount of air going into the engine. If a throttle body is failing the engine will not get the correct mixture of air and fuel. This can trigger the Reduced Power light as well as lead to a poor running engine.
The most likely issue is that a component is clogged. A clogged fuel filter is the most common reason, although a loss of power in your car could also indicate problems with the fuel pump or fuel line. Impurities or debris may be blocking the system, which causes the loss of power in a car.
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.
Will your check engine light turn off by itself? In most cases, successfully repairing the issue that caused your light to come on will cause the check engine light to turn off automatically—but only after 10 to 20 “cycles”.
Check your gas cap first. Many vehicles have a loose gas cap indicator that will be triggered before your check engine light comes on. If your gas cap is loose or the seal is not tight, the vapor leakage can cause your fuel system to trigger the check engine light.
A check-engine light will shut itself off if the condition that caused it is remedied. So, if your converter is marginal, and you did a lot of stop-and-go driving, which creates high demand for the converter, that might have turned on the check-engine light.
Culprits include a dirty fuel filter, clogged fuel tank strainer, clogged or failing fuel injectors, or a defective fuel pump. On most vehicles replacing the fuel filter is a DIY operation.
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 Power Loss
Your high-performance engine will lag if the O2 sensor is bad and tricking the engine control unit (ECU) into putting too much air in the combustion chamber. This creates a lean fuel mixture in the chamber and causes sputtering and power loss in the engine.
The 2011 Cruze problems include jerky acceleration and electrical system flaws. Transmission failures are the most common problem. Failures happen around 65,000 miles, and require a complete replacement. Frequent engine problems are also noted, including issues with the throttle body and intake manifold.
Often, the problems are minor. In rare cases, though, reduced power can cause more serious problems like a seized engine, or even an electrical fire.
An abrupt loss of engine power is a somewhat obvious sign of a fuel injector failure. If the fuel injector is clogged, the fuel supply will be irregular too. When the fuel level fluctuates drastically, the high and low rpm`s will cause the engine to move in surges rather than slow and gradual movements.
The accelerator pedal sensor (APS) indicates the position of the accelerator on vehicle models with electronic throttle control. The APS is basically a throttle position sensor (TPS) with a pedal attached.
(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.
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.
New spark plugs can also help increase your car`s power and acceleration, making it easier to get up to speed (literally). In addition, new spark plugs can also help reduce emissions from your car`s engine.
A good spark will be blue-white and will be plainly visible in daylight. If a good spark is present, the problem is probably not in the ignition system. Check the fuel system and/or stark timing. Weak sparks are orange or red and may be hard to see in daylight.
