1998 Jeep grand cherokee throttle body shaft intake leak

I have a 98 grand cherokee limited straight-6 4.0L that's been running rough for months. i finally got around to running a smoke test through the intake manifold and the smoke was pouring out around the throttle body shaft, at least that's what my buddy said it was. it was coming from b/w the throttle spring and the shaft. i just found this tonight, is there something in there like an o-ring or bushing or seal i can replace? what's my best bet at this point? i appreciate any feedback, thanks!

Where is the throttle positions sensor located


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

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.

Rough idle comes and goes.all new plugs ,wires, cap,rotor,complete distributor,comp checked,new o2's ,chkd for vacum leaks.lots more parts.no ck engine light?


Idle air control motor can stick sometimes. it's on the side of the throttle body. pull it off and clean it with brake clean, also clean the throttle body behind the plate and in it as far as you can. use a small brush. Tooth brush works great.

98 jeep grand cherokee limited 4.0 litre. starts up, during warm up process engine will idle irradically and stall out. starts back up and does the same thing. no check engine light on. cleanrd throttle...


Does this thing have a throttle body that looks like a computer-controlled carburetor?

If so, start motor and verify that it behaves irratically and then stalls.

then, spray WD-40 liberally around base of throttle body where tb meets intake manifold.

Start motor...

Does the problem go away, at least whilst for a little while?

Yes?

You gotta vacuum leak. Replace gasket under TB and tighten bolts to factory spec.
