The problems you are having may be due to a sticking throttle control, or possibly a transmission shifter control problem. These vehicles have an electronic throttle and if you try to push on the brakes and the throttle at the...
The idle is controlled by the idle air control valve and if it cannot keep the engine idling it will keep trying to rev the engine up to compensate. A vacuum leak, sensor that has failed, or an EGR system...
Hi there. It seems that your issue is the fuel pressure regulator has failed. The fuel pressure regulator is designed to adjust the fuel pressure to the injectors after the fuel pump pushes the fuel to the rail under max...
Hi there. For the engine revving up and the vehicle slowing down, the transmission could be slipping. Check the transmission fluid and see if its full and red in color. If the fluid is full, then the transmission could be...
Hi there. What happened is the voltage regulator in the alternator failed. The battery died due to the alternator not putting the voltage back into the battery, but instead it cooked the battery with a higher voltage than the battery...
Hi there. The problem lies within the gas pedal. The pedal position sensor has lost its counts and is telling the computer to rev up the engine to a higher count, but the sensor will not deactivate until the brakes...
The engine computer has a built in rev limiter built in to the programming that will not let the engine go above 3800 to 4000 rpms when the transmission is not in gear and driving down the street. This is...
The issue you're describing is typically an indicator of an internal transmission component failure or loss of hydraulic pressure inside the transmission. The change of the motor and transmission mounts probably did not hurt the Honda's ability to accelerate correctly....
Hello - yes, you probably need a new throttle position sensor. The symptoms you describe are classic throttle position sensor failure symptoms. I would recommend having a Throttle Position Sensor Replacement Service (https://www.yourmechanic.com/services/throttle-position-sensor-replacement) completed by a mobile, professional mechanic, such...
Hey there. This may be related to a dirty or failing idle air control valve. The idle air control valve monitors the air intake as it is mixed with fuel prior to being injected into the engine at low speeds...
Hello. The throttle cable (https://www.yourmechanic.com/services/throttle-control-cable-replacement) could be sticking causing the RPMs to increase excessively if the throttle cable is holding the throttle open when it shouldn’t be. There also could be a bad throttle position sensor (https://www.yourmechanic.com/services/throttle-position-sensor-replacement) or idle control...
Air leaks into the intake system (a loose hose, or the EVAP valve as you have already experienced). If there are no codes, even transient codes which may not set the Check Engine Light, the problem could be a loose...
Hi there. Check the engine for a vacuum leak. Check all vacuum lines, hoses, and the intake for any leaks. Also check the brake booster for any leaks. A vacuum leak will increase the engine's idle speed while the engine...
This is normal for your vehicle. The vehicle is designed not to be overrevved when it is in park. When you start driving the computer recognizes this and allows it to rev higher. I would not worry about this unless...
Hi there. Check the engine for any oil leaks that are visible to you. Check the front seal, the oil pan, the oil filter, the oil drain plug (make sure its tight), the valve cover gaskets, the oil cooler lines,...
Hi there. According to the shifting charts to your transmission, third and fourth gear both use the Overdrive Clutch as a holder to get the gears with the Underdrive Clutch and the Fourth Clutch. Since your vehicle will only get...
Hi there: The idle is controlled by the idle control valve (https://www.yourmechanic.com/services/idle-control-valve-replacement), mass air flow sensor (https://www.yourmechanic.com/services/mass-airflow-sensor-replacement), and throttle body (https://www.yourmechanic.com/services/throttle-body-replacement) of a fuel injected motor. Any of these components could be dirty, damaged, or have faulty wiring that is...
This may be related to a dirty or failing idle air control valve. The idle air control valve reads the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and at...
This may be a sign of a failing throttle position sensor (https://www.yourmechanic.com/services/throttle-position-sensor-replacement). The throttle position sensor (TPS) is a sensor used to monitor the throttle position of the throttle plate inside the throttle body in relation to your foot position...
Hey there. Even though you've cleaned the idle air control valve (https://www.yourmechanic.com/services/idle-control-valve-replacement), that doesn't guarantee that the valve isn't still sticking or otherwise malfunctioning. You could try very gently tapping on the valve and see if that affects engine speed....
