If the light is flashing then the computer system should have stored codes as to why the problem is happening. I recommend having the computer scanned by a certified technician, such as one from YourMechanic, to retrieve the codes and have them diagnosed. If there is a misfire code then that cylinder should be checked for problems with fuel, spark, or compression issues by the mechanic testing the vehicle for you.
How to Identify and Fix Common car Problems ?

A Reduced Power light usually indicates a fairly serious problem with the throttle system. When this light illuminates the vehicle will often go into a “safe mode”, which will severely limit the speed of the car and in some cases will render the vehicle un-drivable.
If the check engine light in your Lexus starts flashing, that means that the problem needs abrupt attention and your Lexus should be brought in hastily. This shining light usually indicates a persuasive engine misfire allowing unburned fuel to be drained into the exhaust system.
A Check Engine indicator will stay solid or blink. If the indicator is blinking, the situation is usually serious, such as a severe misfiring of the engine. This would allow unburned fuel to dump into the exhaust system, pushing the temperature of your catalytic converter to the breaking point.
The check engine light can either come on and stay lit or blink, depending on the type of problem. Typically, when a check engine light flashes rapidly, it indicates a power loss in the vehicle or something even more urgent.
Faulty throttle and pedal position sensor Any problem within the TAC system can cause the reduced engine power warning light to go on. One of the more common reasons includes one or both APP sensors in the accelerator pedal or the pair of TP sensors.
Shut off the engine, wait 10 seconds, then restart the vehicle to see if this resets the reduced engine power light—but this will only work if it`s a signal error. Avoid driving your vehicle when the reduced engine power light is on—instead, identify and repair the underlying problem that`s causing the warning light.
What a Blinking Light Means. It could be overheating or an oil pressure issue. It could also be a problem with the brakes or fuel line, belt, hoses, etc. By far, though, the most common is a misfire in the engine that can damage the catalytic converter.
A solid check engine light indicates a problem that needs to be addressed but is typically not urgent. A flashing check engine light indicates a severe problem that requires immediate attention to avoid further damage.
If your check engine light is flashing, something is wrong with your engine. You need to pull over and shut it off as soon as it`s safe to do so. The check engine light flashing when accelerating combined with white exhaust appearing and disappearing suggests a sticking fuel injector.
In order to disable these systems, you`ll want to press and hold the TRAC/VSC switch for more than three seconds while the car is stopped. The VSC OFF indicator light should then come on, and a “Traction Control Turned Off” message should be shown on the multi-information display.
Sometimes, the check engine light comes on to let you know that there`s a problem with the car`s internal diagnostic mechanism. That means the system could be “finding” a problem that doesn`t exist, or it could be that loose wire systems are creating a false positive in the system.
Worn/failed spark plugs, coil packs, or spark plug wires can trigger your check engine light to come on. In today`s cars, say Firestone Complete Auto Care technicians, if a plug starts to fail then the most obvious event should be the check engine light coming on or even flashing.
Will a bad O2 sensor cause rough idle and loss of engine power? You bet. Moreover, you may also notice poor acceleration, engine misfires, and even stalling.
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.
As the MAP sensor fails, it can cause various issues with the fuel system and vehicle performance. An inaccurate reading from the sensor will cause the computer to change the amount of fuel it sends, which can rob the engine of power or cause it to run poorly.
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.
The most common and relevant cause of a P0300 code is spark plugs that are damaged or worn. This is also a common cause among additional codes displayed as P030X. Spark plugs are devices that ignite the compressed mixture of air and fuel in each cylinder of an internal combustion engine.
It is generally safe to drive with the “Reduced Engine Power” light on, but you should take your car to a mechanic as soon as possible to avoid further damage.
A steady check engine light indicates a non-emergency issue, such as a loose gas cap. Flashing check engine lights warn of severe situations requiring immediate attention. Standardized diagnostic codes help identify the trouble.
It is generally safe to drive with the “Reduced Engine Power” light on, but you should take your car to a mechanic as soon as possible to avoid further damage.
Expect to pay between $100 and $500, including parts and labor, to get your engine back in shape. However, a catalytic converter issue can cost over $2,000.

Reduced Engine Power signifies that the car has lost some power and isn`t performing as it should. Common cause include reduced flow of fuel and/or air to the engine, clogged catalytic converter, problem with the air intake, or a dirty mass airflow sensor.
