I have a 2007 California Special it has it takes when I step on the acceleration pedal now it acts like it wants to die is it a throttle body issue

Question edited for clarity.

Did you clean it properly both sides, fully disconnect it? You need to do a Throttle Body Re-learn.

The 2007 Ford Explorer Sport Trac does not utilize the once-common idle air control (IAC) valve. Instead, an electronic throttle body is used. An electronic throttle body is a traditional butterfly throttle valve that has an electric motor attached to it. Instead of opening via a throttle cable, it is opened by the powertrain control module (PCM) when the accelerator pedal position (APP) sensor (which is the gas pedal) is pressed. The PCM also adjusted the throttle blade position in order to achieve proper idle speeds. Often times idle problems with this type of electronic throttle body are caused by carbon buildup around the throttle plate, in the bore of the throttle body. In fact, this is such a common problem with this particular vehicle that Ford released technical service bulletin (TSB) #12-7-4 to address the RPM fluctuation and hard start symptoms and advises to clean the throttle body. Alternatively, the throttle body can and may need to be replaced.

Check for vacuum leaks, fuel pressure and fuel filter. Also clean the throttle blades on the Throttlebody.

Your vehicle has electronic throttle control , position sensors in the accelerator pedal ,position sensors in the throttle body . A REDUCED POWER message is suppose to warn the drive so it takes it to a quaified repair shop ,DEALER !
Cleaned MAF & throttle body & changed crank position sensor. Not just replace parts blindly .

I post this recommendation often as most people do not know about it. Your throttle body is gunked up to kingdom come with engine grime and is sticking not allowing the proper amount of air to get into your engine.

Your specific scenario sounds like the engine computer is not able to adequately adjust air coming into the engine and if you do not rev the engine, forcing the throttle body open the engine will choke out literally and die.

CLEAN the throttle body. there is a metal flap inside that is getting stuck. Check here to see a clean throttle body

Here is the quick and dirty: Your gas pedal is hooked up to a wire or motor that turns a flap open and closed and various degrees of open and closed as you apply and take pressure off of the pedal. this flapper gets gunked up and sticks. it is the sticking that causes your car to choke and die :)

Go buy CRC Throttle Body Cleaner and remove the throttle body and spray that in there and wipe clean with a towel.

Search forums for vehicle specific instructions on how to remove the throttle body and clean it. Guaranteed you are not the only person with this issue.

I will try and help for your Nissan Sentra


1. Open the hood, look at then engine.
2. On the right side there will be an air intake tube that is black and hooked up to your air box and throttle body with hose clamps
3. Losen the hose clamp from the throttle body and remove the black air hose from it and gently move it out of the way.
--> If you do not want to remove the throttle body completely, skip to step #7
4. there will be 4 bolts holding the throttle body to the intake manifold.
5. Note any and all electrical connections to the throttle body.
6. Remove the electrical connections (unplug) and remove the bolts (4) and the throttle body should come off.
7. Spray CRC Throttle Body Cleaner all over and wipe clean with a cloth that can get really dirty.
8. Make it SHINE :) then reinstall
9. put 4 bolts back on, reconnect the electrical connections you remembered from step #5
10. Reconnect the black air hose and tighten the hose clamp...

Done!

Start the car and it should be good as new. (sort of)

Hi, if you don't have a manual, you can get a free download here: http://www.dodge.com/en/owners/manuals/

The lightning bolt indicates a fault in the electronic throttle control. It is likely the rheostat/potentiometer in the accelerator position sensor is dirty or worn out. I have pasted info on the part below from autozone.com. If you replace the sensor, be sure to follow the calibration procedure at the end of the installation instructions. Please let me know if you have any questions and thanks for using FixYa.

Operation
The Accelerator Pedal Position Sensor (APPS) assembly is located under the vehicle battery tray. A cable connects the assembly to the accelerator pedal. A plastic cover with a movable door is used to cover the assembly.


NOTE The APPS is used only with the 5.7L V-8 engine.

The Accelerator Pedal Position Sensor (APPS) is a linear potentiometer. It provides the Powertrain Control Module (PCM) with a DC voltage signal proportional to the angle, or position of the accelerator pedal. The APPS signal is translated (along with other sensors) to place the throttle plate (within the throttle body) to a pre-determined position.
A mechanical cable is used between the accelerator pedal and the APPS assembly. Although a cable is used between the pedal and APPS, a mechanical cable is not used at the throttle body. Throttle plate position is electrically determined.
The Accelerator Pedal Position Sensor (APPS) assembly is located under the vehicle battery tray. A cable connects the assembly to the accelerator pedal. A plastic cover with a movable door is used to cover the assembly.

Removal & Installation
The APPS is serviced (replaced) as one assembly including the sensor, plastic housing and cable. The APPS assembly is located under the vehicle battery tray. Access to APPS is gained from over top of left / front tire.

1. Disconnect negative battery cable at battery.
2. Disconnect APPS cable at accelerator pedal.
3. Remove wheel house liner at left / front wheel.
4. Gain access to APPS electrical connector by opening swing-down door.
5. Disconnect electrical connector.
6. Remove 3 mounting bolts.
7. Remove APPS assembly from battery tray.
8. If cable is to be separated at APPS, unsnap cable clip from ball socket. Release cable from plastic housing by pressing on small cable release tab.

To Install:

1. Install Accelerator Pedal Position Sensor (APPS) cable to accelerator pedal. Refer to Accelerator Pedal Removal / Installation.
2. Connect electrical connector to APPS.
3. If necessary, connect cable to APPS lever ball socket (snaps on).
4. Snap APPS cable cover closed.
5. Position APPS assembly to bottom of battery tray and install 3 bolts.
6. Install wheelhouse liner.
7. The 5.7L V-8 engine is equipped with a fully electronic accelerator pedal position sensor. If equipped with a 5.7L, also perform the following 3 steps:
   1. Connect negative battery cable to battery.
   2. Turn ignition switch ON, but do not crank engine.
   3. Leave ignition switch ON for a minimum of 10 seconds. This will allow PCM to learn electrical parameters.
      NOTE The DRB III Scan Tool may also be used to learn electrical parameters. Go to the Miscellaneous menu, and then select ETC Learn.
      
   
   
8. If the previous step is not performed, a Diagnostic Trouble Code (DTC) will be set.
9. If necessary, use a proper scan tool to erase any Diagnostic Trouble Codes (DTCs) from PCM.

Check the vehicle for DTC'S - diagnostic trouble code's should be the first step in diagnosing this problem . But a tune - up not ! Reduced enging power is caused by a problem with the electronic throttle control . If you are not familiar with this ,your best bet would be to take to a qualified repair shop.
REDUCED ENGINE POWER: Refer to Powertrain Control Module Description in Engine Controls - 4.8L, 5.3L, and 6.0L

Throttle Actuator Control (TAC) Overview
The throttle actuator control (TAC) system uses vehicle electronics and components to calculate and control the position of the throttle blade. This eliminates the need for a mechanical cable attachment from the accelerator pedal to the throttle body. This system also performs the cruise control functions as well.
The TAC system components include, but are not limited to the following:
• The accelerator pedal position (APP) sensors
• The throttle body
• The powertrain control module (PCM)
Each of these components interface together to ensure accurate calculations and control of the throttle position (TP)
Accelerator Pedal Position (APP) Sensor
The APP sensor is mounted on the accelerator pedal assembly. The APP is actually 2 individual APP sensors within 1 housing. There are 2 separate signal, low reference, and 5-volt reference circuits. APP sensor 1 voltage increases as the accelerator pedal is depressed. APP sensor 2 voltage decreases as the accelerator pedal is depressed.

One of these sensors could be sending conflicting data to the PCM - engine computer .

Reduced Engine Power Mode
When the PCM detects a problem with the throttle actuator control (TAC) system the PCM enters one of the following Reduced Engine Power Modes:
• Acceleration Limiting--The control module will continue to use the accelerator pedal for throttle control, however the vehicle acceleration is limited.
• Limited Throttle Mode--The control module will continue to use the accelerator pedal for throttle control, however the maximum throttle opening is limited.
• Throttle Default Mode--The control module will turn off the throttle actuator.
• Forced Idle Mode--The control module will perform the following actions:
- Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned off.
- Ignore accelerator pedal input.
• Engine Shutdown Mode--The control module will disable fuel and de-energize the throttle actuator.

Throttle Body Assembly
The throttle body for the throttle actuator control (TAC) system is similar to a conventional throttle body with several exceptions. One exception being the use of a motor to control the throttle position instead of a mechanical cable. Another exception is the throttle position (TP) sensor. The TP sensor is mounted in the throttle body assembly. The TP sensor is 2 individual TP sensors within the throttle body assembly. Two separate signal, low reference, and 5-volt reference circuits are used to connect the TP sensors and the powertrain control module (PCM). TP sensor 2 signal voltage increases as the throttle opens. TP sensor 1 signal voltage decreases as the throttle opens.

DIRTY AIR FILTER AND DIRTY FUEL INJECTORS.PARTIALLY CLOGGED FUEL FILTER.YOU COULD HAVE DIRTY THROTTLE PLATES ON THROTTLE BODY HAS A SLIGHT CARBON BUILT UP AROUND THE PLATES.

check the gas cable at the throttle body under the hood, it is possible the cable has either broken or become dis connected. remove the air cleaner and look into throttle body and find the rotating shaft that opens and closes the plate inside throttle body. 1) when you rotate does plate move? 2) is there cable attached to pulley? 3) when someone steps on pedal does the plate move? 1 not likely issue, 2 might be issue reattach cable to pulley, 3 pedal does not move pulley cable disconnected at pedal reconnect there or cable is broken replace cable. if non of these then throttle position sensor may be bad and check or replace
