Hi there. From the description you have provided, there is several possibilities for your vehicle’s drivability problems. Your vehicle’s Check Engine Light may help diagnose the lack of power and inoperative cruise control. Accessing the vehicle’s computer for codes stored, could direct you to the area of concern. The vehicle’s lack of power does not sound like a transmission or timing chain issue. It could be a fuel pump volume problem. It could be a restricted exhaust system ie; partially plugged catalytic converter. The inoperative cruise control could be related to the lack of power. I recommend your vehicle’s lack of power diagnosed and repaired by a certified technician from YourMechanic.

If the check engine light happened to be flashing during these episodes of acceleration, that means there is a serious fault, such as cylinder misfiring, that requires immediate repair. Misfiring, in particular, has the potential to damage the catalytic converter which can result in additional costly repairs.
The most common reasons a Dodge Grand Caravan has a check engine light are an emissions system component, a sensor, or a catalytic converter.
A blinking check engine light will show up on your dashboard is almost always correlated with engine misfires. A misfire means that the engine is dumping uncombusted fuel into your car`s exhaust system. Engine misfire is a serious issue because it can quickly raise the temperature of the catalytic converter.
Multiple reasons can cause this, such as a clogged air or fuel filter, a weak fuel pump, or defective spark plugs. Moreover, in the case of modern cars, an engine misfire can result from sensor problems such as a bad oxygen sensor or a faulty mass air flow sensor.
It is responsible for how quickly the car can accelerate and helps you go from 0-60 mph in a matter of seconds. The up-and-down motion of the pistons in your engine produces force. The force is then transferred to your wheels which in turn causes the car to go.
Bad gas can directly affect your ability to accelerate on the road. If any portion of your gas is not as quality as the rest, you may notice varying degrees of power, seemingly randomly, within even one tank of gas. It is important to test the acceleration power of a car when test driving any new or used vehicle.
A steady glow typically means something less serious but a flashing check engine light indicates that your vehicle`s engine is in serious trouble and service is needed immediately. If your check engine light is flashing in your Dodge, we highly recommend not to drive the vehicle and schedule Dodge service today.
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.
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.
While acceleration will never damage your engine in the same way as, say, hitting a tree at 60mph, it does cause damage in the long term. Quick acceleration puts a lot more stress on your engine than gentle increases in speed, contributing to engine wear and damage, even if you don`t notice the changes right away.
Limp mode is a car security feature that activates when a fault is detected, reducing speed and switching off non-essential functions. It is triggered by abnormal signals from car components, such as faulty sensors, transmission issues, or low fluid levels.
When there is a problem with the throttle body, the check engine light may come on. That doesn`t mean when the lights come on, then it has to be about the throttle body. The light can come on because of another problem with the engine. If it comes on, call a mechanic to diagnose the source of the problem.
Your car jerking when accelerating and the check engine light coming on at the same time usually means you have a problem with your car`s fuel injector, ignition system, spark plugs, or catalytic converter. Scanning your car computer for trouble codes that triggered the CEL to illuminate is a good starting point.

Car won’t start, check engine light is out but other lights are on, got new control and immobilizer but the problem remains.
ANSWER : Hi, thanks for writing in. It is possible that your check engine light bulb could be out. I would recommend having a qualified professional remove your instrument cluster to determine if the bulb for the check engine light has failed. If the bulb has failed, I would recommend having it replaced and see if your results change. If the bulb is not faulty, it is possible that something was installed incorrectly during the most recent repair. I would recommend retracing your steps to determine if any steps were skipped over or done improperly. This will help to determine the cause of why the check engine light will not work. If you would like help, consider having an expert automotive technician from YourMechanic come to your home or office to inspect your electrical system for you, and make or suggest any repairs as needed.
Honda Civic 2008. AC stopped working suddenly and engine check light came ON for a day.Next day AC worked and no engine light.
ANSWER : Hi there. In both cases, when an AC system is not working and a warning light is coming on the dashboard, typically a professional mechanic will complete the same initial inspection, which is to download the stored error codes that triggered the warning light initially. This tends to give them an idea as to what is causing the problems. This could be something as simple as an electrical relay that is faulty or loose or an indication of a computer related "glitch". Either way, the best way to move forward is to have a professional mobile mechanic complete a check engine light inspection.
Traction light/reduced engine power and check engine light coming on
ANSWER : Hello. From what you describe, it would appear that your vehicle may be experiencing some sort of intermittent wiring or sensor issue. If the problem occurred again after driving over a bump, then it may be possible that a damaged or loose wire is shorting or having contact issues. A common issue that can cause stalling is a faulty crank position sensor or wiring. I would carefully examine the engine for any loose or damaged wires. If the Check Engine Light comes back on, I would recommend having the trouble codes scanned before resetting the computer.
My check engine light and traction control lights are on and the cruise control light is flashing on and off.
ANSWER : Hi There,
What you are describing is common for a vehicle with traction control when it has been activated in a situation as you have described. The cruise control is also controlled in some cases by the traction control system and may be flashing as a need to have it reset due to the traction control being activated under those circumstances. The traction control system monitors the steering stability of the vehicle and engages when loss of traction has been detected. This is done by the use of electronic sensors at each of the four wheels that communicate with the Power Train Control Module (PCM) regarding steering performance and stability in adverse weather conditions. The traction control system works by reducing engine speed and determining which wheel to apply brake pressure to in order to prevent the vehicle from sliding. The anti-lock braking system and the traction control system work together to maintain the stability of the vehicle. The computer uses this information received from electronic sensors regarding the rotational speed of each wheel, the horizontal motion of the vehicle, and the vertical motion of the vehicle to determine how to direct the traction control system or the anti-lock braking system to best control the vehicle when needed. In some cases, the traction control system may simply need to be reprogrammed. I would recommend having a professional from YourMechanic come to your location to properly diagnose your traction control system.

2012 equinox reduced power light engine light and traction light came on. Lost a lot of power got home and all light except engine
ANSWER : Your car has what is called a "safe mode" that will be engaged by the computer when it detects that something critical has gone wrong related to any of the major components in your engine chassis or power train. This may be related to a number of things, most of which should have been registered in the computer when the check engine light came on. I recommend having an expert from YourMechanic come to your location to inspect your check engine light and diagnose any codes registered by your vehicle’s computer.
Reduce engine power / check engine light is on
ANSWER : Hi there. Most of the time, reduced engine power is caused by a restriction of fuel, or the throttle body’s inability to efficiently mix air and fuel. This could be caused by a failing mass air flow sensor, EGR valve or other fuel system components. Since the check engine light is on, you should have a professional mechanic complete an inspection at your location to determine what codes are stored and which components require repair. This should resolve your issue.
Car started to slow down and then the check engine light, battery, and engine oil light came on. What could cause this?
ANSWER : Hi there. It is possible that the battery cable came loose or the wires to the oil pressure sensor has came loose or failed. Check the battery cables and make sure that the terminals are tight and clean. Check the wires to the oil pressure sensor and make sure that they are connected and not broken. If everything looks good, then the oil pressure sensor may have failed. Plus, check the computer for codes and see what is stored. This will lead you to the part that could have failed. I recommend replacing the oil pressure sensor then checking to see if the lights will go out. If you need further assistance troubleshooting your vehicle, then seek out a technician, such as one from Your Mechanic, that can assist you with the warning lights that came on.
