That is the torque converter clutch circuit. Have the torque converter switch and/or relay switch checked, or torque converter lock up switch.

Most common failure is crank sensor. Before running out and buying one, I strongly recommend that you do some further testing. Any decent manual has instructions for testing systems. Also: test both running and after it dies. (while running everything may check out as good) If you have spark when not running, check fuel filter as well!

I'm not sure if this applies to your vehicle but often a vaccuum reserve tank is used in the system to eliminate this problem. If you have one, make sure it's not leaking. If you don't and were supposed to, someone may have removed it. There also may be a check valve in the line somewhere that is malfunctioning. This used to happen on older vehicles with vaccuum wipers. They would almost stop when going uphill. It's the same thing, just on a different system! Could also be a slight bleed-off from a plenum door motor that is not bad enough to not work, but just enough to react to low vaccuum caused naturally when engine is working hard.

Sounds like there is water getting into the diff. Most of the time it is from the vent on the top. That will cause damage to the bearings and make noise.

have you check the alternator possible problem. if not that you have a draw on the battery with the key off. you need an amp meter one that will clip around the positive cable from the battery this will tell you if your vehicle has a parasitic draw with the key off. most parts stores have loaner tools you can use. hope this helps some.

Its a mess. Takes several hours. Requires complete removal of dash. Costs $800-1500 at an AC repair or dealer shop.

this is either the clutch pressure plate or the transmission main shaft rattling due to worn bearings or the pilot bearing is worn out.

Try holding your gas pedal all the way down while starting.

The contacts for the third brake light are two silver discs, about the size of a dime. They are located on the inside of the tailgate, hinge side. Make sure your carpet or any other loose item has not covered one or both contacts. Make sure they are fairly clean and make good contact.

Try the crankshaft sensor.

It does'nt have to be OEM Jeep oil.
As long as the viscosity is the same you will not have a problem.

You are losing vacuum source to the system.
There should be some kind of vacuum reservoir under the hood.

Have a look at the cable where it hooks up to the throttle body.
Have someone push down on the accelarator while you look, make sure the throttle body is opening all the way.

There is no fix.
The top has to be installed and pulled back along the sides so you have minimal gap at the zippers.
You can also get a new top.
