you more than likely have a vaccum leak or you have a bad fuel pressure regulating valve. Could be one or more good luck.
It has to be replaced. no adjustments.
The Throttle Position Sensor is conneceted to the end of the Throttle Shaft inside the Throttle Body. P.S. The Throttle Position Sensor is part of the Throttle Body and must be replaced as a unit. Hope this helps ya.
The throttle position sensor is actually apart of the throttle plate actuator assembly and must be replaced as a unit.
The Throttle Position Sensor (TPS) is located in the throttle body a the end of the shaft opposite the throttle cable attachment. Some are permanent / no serviceable. Some can be replaced and with a little ingenuity/skill, even the permanent can be replaced as there are replacements available for all year models.
It's part of the throttle body, entire unit must be replaced.
Sounds like the throttle sensor, throttle body needs to be replaced.
the throttle cable itself will have to be replaced. the cable is most likely fraying internally.
clean the throttle body
The throttle position sensor determines the amount of throttle used when the engine is running at various speeds. If the sensor is faulty, it can be replaced by ordering a new part.
Needs adjusted or replaced.
There is no reset. If failed the part must be replaced.
I have a 2004 Alero and I just figured out today and replaced my throttle positon 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. http://en.wikipedia.org/wiki/Throttle_position_sensor
