If you are referring to the MAF(Mass Airflow Sensor),it will cause this exact problem if it is installed backwards.(I see many car build shows,and they get it wrong so much,I thinks they are doing it on purpose to make the show more interesting).

Throttle positing senser on a 99ranger I changed it now the idle is way to high


The positioning of the new TPS IS OFFSET....It is possible to install it wrong by accident..I have seen this happen before..The pressure from the sensor plastic actuator has been installed and slightly twisted against the throttle lever inside which causes throttle to raise slightly....Wear safety glasses and disconnect battery..Remove sensor slowly and carefully while removing and watch the throttle lever inside to see if it moves in any direction...Carefully install it again making sure it doesn't twist the throttle lever inside where sensor mounts...The lever on the sensor should stay in its position...Carefully install sensor making sure it doesn't twist...Connect wiring and battery and start for a safety check.....It is possible to have a wrong sensor or faulty new sensor...Double check that it is the correct sensor...

How to replace the TPS.


no engine option stated, and is key fact to know here.
eg:
The 5.7L V8 engine does not use a separate Throttle Position Sensor (TPS) on the throttle body.

remove old TPS, and bolt on new.
its like 2 or 3 screws. no big deal.
but needs to be calibrated per fsm.
ill take a wild guess, 3.7L
3.7L Engine and 4.7.
  1. Remove air resonator tube at throttle body.
  2. Disconnect TPS electrical connector.
  3. Remove two TPS mounting screws.
  4. Remove TPS.
install
The throttle shaft end of throttle body slides into a socket in TPS. The TPS must be installed so that it can be rotated a few degrees. (If sensor will not rotate, install sensor with throttle shaft on other side of socket tangs). The TPS will be under slight tension when rotated.
  1. Install TPS and retaining screws.
  2. Tighten screws to 60 inch lbs. (7 Nm) torque.
  3. Connect TPS electrical connector to TPS.
  4. Manually operate throttle (by hand) to check for any TPS binding before starting engine.
  5. Install air cleaner tube to throttle body.
some TPS need calibration
to see what yours needs, read the FSM
or at alldata.com
or here. I think all engines here, are TPS PCM autocalibrated.

Engine stalls under acceleration, shows code P1580, changed throttle body with new one but problem persists


I would worry or be concerned about the code.
The code is about the throttle sensor or actuator. If the sensor is faulty or the computer is not getting a good signal from the sensor it does not know what the throttle position is.
You might try resetting the throttle position - clear the code, key on but don't start, hold pedal to the floor, key off.

Where is the throttle positions sensor located


The Throttle Position Sensor, or TPS is connected to the throttle shaft on the throttle body.

zjlimited_2070.jpg

Fig. 2: Disengage the Throttle Position Sensor (TPS) wiring harness connector

According with the Grand Cherokee Repair Manual, check this removal & installation procedure...
(see Figures 5 and 6)
  1. Remove the air intake tube at the throttle body.
  2. Disengage the TPS wiring connector and remove the two mounting screws.
  3. Carefully remove the TPS from the throttle body.
To install:
  1. The throttle shaft end has a tang that can be fitted into the TPS two different ways. Only one of the installed positions is correct. When correctly positioned, the TPS can be rotated a few degrees. To determine correct positioning, place the TPS onto the throttle body with the throttle shaft tang on one side of the TPS socket. Verify that the TPS can be rotated. If the TPS cannot be rotated, place the TPS on the throttle body with the throttle shaft tang on the other side.
  2. Tighten the two TPS mounting bolts to 60 inch lbs. (7 Nm) and engage the wiring connector.
  3. Manually operate the throttle and check for any binding.
  4. Install the air intake tube.

Additionally, its possible that you are interesting in some section about this repair manual: Jeep Grand Cherokee 1993-1998 (ZJ Series).

Hope this helps; just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment. Thank you for using FixYa.

Lack of power


If your problems started from the day that you had the new throttle body installed, yes this may be your problem. I'll give you some checks that you may perform to check if it was installed properly.

1.Make sure that all the hoses were replaced and all hose clamps were tightened up properly, if it leaks air, your air flow sensor wont be able to read the correct air flow into the egine which leads to poor performance.

2. If it is second hand throttle body that was installed, move your throttle shaft where the accelerator cable is attached to, up and down. If there is a lot of movement you will have to replace it or get it re-bushed.

3.On the side of the throttle body is a black unit attached, this is your throttle position sensor. With the egine not running, move the throttle on the throttle body, you should hear a click sound (a micro switch inside this unit opens a circuit), if you do not hear a click sound it has been set up incorrectly. Loosen up the two bolts holding this unit to the throttle body and turn this unit in the opposite direction of the throttle to rev up the engine if it was running, then turn it in the same direction as if you would throttle the engine but do it slowly untill you can hear a click sound. As soon as it clicks hold it and tighten the lock bolts. Now test it and make sure as soon as you would accelerate it clicks, job done for this one.

Generally look for vacuum hoses that might not be connected or secured properly and or electrical connections that might not be in place.

near the throttle body part there is a electronic idle control valve either this control valve is defect or there is a leak between the body and the valve.
