HIGH IDLING Replaced thottle body sensor, did not take of the problem

That error is not the O2 sensor. It is tjhe throttle or gas pedal postion sensor. It is on the floorboard attached to the foot feed for the throttle. IT gets dirty, wet, loose etc. Check it, clean it, reseat it and if all else fails...replace it.

check for vacume leak, if the check engin light is on have it scaned
throttle position sensor could be causing the problem but most likely its the idle air controll motor stuck fully open located on the thottle body not bad to replace held on by 2 torks hed srews

Try checking the adjustment screw on the throttle body. Two other possible causes could be the speed sensor or the TPS sensor.

high RPMs is the sign of a bad idle air control valve. it is located on the thottle body next to the throttle posistion sensor

I, feel sorry for you, after reading your problem, but don't worry you visit the Reliable-Store they will help you for sure.

The TPS ( THOTTLE POSITION SENSOR) tells the engine computer and trans how far you are pushing the gas pedal. Its mounted on the side of the thottle body. It will make the engine surge if it is failing. Have replaced this part many times for this problem. TCM (TRANS CONTROL MODULE) control trans shifting. The tps is and one of the input sensor for shifting.

It sounds to me like you have replaced everything except the most likely cause of your idle control problem...The Idle Air control. (IAC) (or Idle Speed Control Valve) It is located onthe throttle body and looks like the picture below.

p2106 Throttle actuator control system-Forced limited power.

the tp sensor/s in your thottle body is the problem. the most common repair is to replace the thottle body, some people just replace the tp sensors.

It also can be a broken wire to the injector.

the throttle body injector gaskets eed to be replaced.

Change your Thottle positioning Sensor. My 93 lesabre did the same thing and i changed the TPS and it stopped.
