How do you remove the throttle cable on an 1988 Alero?

Accelerator cable may be sticking and not allowing the throttle to fully close when there is no pressure on the gas pedal. Check the cable at the throttle body to make sure the throttle is fully closing. This can also because by a faulty idle air control (IAC) motor.

If you are talking about the "Throttle Position Sensor" you sort-of answered your own question. It is located on the throttle body on the oppsite side of where the throttle cable connects.

Remove the air filter tube, and clean the throttle body with Throttle Body Cleaner and a rag. Make sure all the carbon is removed. DO NOT use Carbuator Cleaner.

Idle Air Control Valve Pintle may be bad If you disconnect the IAC and the problem ceases it can point to this being the problem.: Removal & Installation 3.5L Engine To Remove:

1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
2. Remove the fuel injector sight shield.
3. Drain the cooling system.
4. Remove or disconnect the following:
   • The air cleaner intake duct. Figure of IAC and TPS electrical connectors disconnected.
     
     
   • The idle air control (IAC) valve and throttle position (TP) sensor electrical connectors. Figure of cruise control and throttle control cables removed from throttle lever.
     
     
   • The cruise control cable and throttle control cable from the throttle body lever.
   • The fuel pressure regulator vacuum hose, positive crankcase ventilation (PCV) hose and the throttle body vacuum port hose.
   • The throttle body coolant hoses.
   • The throttle control cable bracket, leaving the throttle and cruise cables connected.
   • The upper nut holding the throttle body to the intake manifold.
   • The throttle body assembly.
5. Clean the gasket mating surfaces.

To Install:

1. Install a new gasket and new studs if necessary.
2. Install or connect the following:
   • The throttle body assembly.
   • Start the top nut by hand.
   • The throttle body coolant hoses.
   • Position the throttle control cable bracket and hand start the retaining nuts and bolt.
   • Torque the three throttle body retaining nuts to 89 in.lbs. (10 Nm). And the bracket retaining bolt to 115 in.lbs. (13 Nm).
   • The throttle body vacuum port hose, PCV valve hose and the fuel pressure regulator hose.
   • The throttle control and cruise control cables to the throttle body lever.
   • The IAC valve and TP sensor electrical connectors.
   • The air intake duct.
3. Refill the cooling system.
4. Install the fuel injector sight shield.

4.0L Engine To Remove:

1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
2. Relieve the fuel system pressure.
3. Remove or disconnect the following:
   • Negative battery cable.
   • The Mass Air Flow (MAF) sensor electrical connector.
   • The air cleaner intake duct.
   • The PCV valve fresh air tube. Figure of cruise control cable removed from throttle cable bracket.
     
     
   • The cruise control cable and throttle control cable from the bracket.
   • The cruise control cable and throttle control cable from throttle body lever. Figure of IAC valve and TPS connectors removed.
     
     
   • The idle air control (IAC) valve and throttle position (TP) sensor electrical connectors. Figure of fuel lines removed from retainer on throttle cable bracket.
     
     
   • The fuel feed and return lines from the retainer on the throttle control cable bracket.
   • The transaxle shift cable clip from the throttle control cable bracket. Figure of throttle body removed from water crossover.
     
     
   • The throttle body from the water crossover.

To Install:
NOTE: The Mass Air Flow (MAF) sensor inlet and the outlet of the air cleaner assembly must line up when installed. Misalignment may cause MIL illumination or driveability concerns.

1. Install or connect the following.
   • The throttle body to the water crossover. Torque the bolts to 106 in.lbs. (12 Nm).
   • The IAC valve and TP sensor electrical connectors.
   • The throttle and cruise control cables to the throttle body lever.
   • The throttle and cruise control cables to the throttle control cable bracket. The transaxle shift cable clip to the throttle control cable bracket.
   • The fuel feed and return line retainer to the throttle control cable bracket.
   • The MAF sensor electrical connector.
   • The air cleaner intake duct clamp. Torque the clamp to 27 in.lbs. (3Nm).
   • The PCV valve fresh air tube.
   • The fuel injector sight shield. Torque the nuts to 20 in.lbs. (2.3 Nm).
2. Install the negative battery cable.
3. Pressurize the fuel system and verify no leaks.

Hi,

I have a 2004 Alero ( similar procedure in your model as well ) and I just figured out today and replaced my throttle position sensor. I'm not sure what the black plastic "box" is called that is above the throttle assembly...but I had to remove that to get to the throttle position sensor underneath. If you can locate the two wires that control the throttle assembly...then the throttle position sensor is on the other side of the throttle assembly. I had to remove the large tube that went from the air filter to the black plastic "box" above the throttle assembly. Also disconnected anything else connected to that black plastic "box". Then pulled that "box" up and right there on the left side of the throttle assembly was the throttle assembly sensor. Here is a web page with a picture that helped me figure out where it was :-

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

When you look down into the throttle body it is the plate that opens when you move the throttle lever (attached to the gas pedal cable)

Look for you throttle cables and where it is attached on engine. It is on the opposite side of the cables.

Bolted to the side of the throttle body.

CLICK HERE to see a generic picture with the sensor mounted on the right side.

Theres a black plastic "box" above the throttle assembly...
Remove that to get to the throttle position sensor underneath.
If you can locate the two wires that control the throttle assembly...then the throttle position sensor is on the other side of the throttle assembly. Remove the large tube that goes from the air filter to the black plastic "box" above the throttle assembly.

Thanks for using FixYa - a Very Helpful rating is appreciated for answering your FREE question.

drain half of coolant out of radiator. remove air filter +air duct from throttle body disconnect all electrical connectors besure to tag them with number so you can put them back in order.remove the accelerator and shift cable on the bracket then remove bracket.remove the air filter box. you have to move throttle body.to make it easy to get to thermostat.then you remove the thermostat hose then housing remove your thermostat.besure to get new throttle body hoses and gasket. make you get the thermostat with the o ring with it.

WELL IT TURNS OUT YOU NEED TO ROTATE THE SPRING TWO ROTATIONS AND CLIP IT TO THE THROTTLE PLATE THAT ATTACHES TO THE THROTTLE CABLE
