I drive a 1996 Jeep Cherokee Sport, manual shift, inline V6 with rear wheel drive.
In the last year I've had the battery, alternator, fuel pump and filter replaced. Today, twice now, when I am coming to a stop and depress the clutch and let off the gas- the jeep simply dies. I can crank it immediately and it runs fine in idle. Both times I was pointed downhill when it died and coasting into my driveway. Could this simply be a dirty throttle body? I am overdue for an oil change.

 

has half a tank of gas with Lucas additive

 

the problem is you have a one of a kind engine. that being the elusive inline v6.

on a serious note its not the throttle body. i suspect a clogged fuel filter maybe. going down hill causing sediment to clog the screen. and stopping flow. then it dies and sediment falls allowing you to start back up.
having reread your post and seeing you replaced your filter. doesn't exactly mean it cant be clogged. if you ran to low on fuel and sucked up all the sediment from the bottom of the tank. I'm probably wrong. but it's not the throttle body.

it might be easier to solve if you establish that going down hill kills it or if the two times were merely coincidence.

good luck

 

ahhh, i did let the tank get very low on gas recently. fume-low. but I've changed this darn filter twice now in 2 years. does that mean my gas tank is most likely in need of replacing or just don't let the fuel get low again?
thanks Mendex

 

It's never a good idea to let the fuel run low on a vehicle with an in-tank pump. The pump is cooled by being submerged in fuel.

I have to agree with Mendax about your problem. Just not enough info right now. Has your check engine light come on yet?

 

Just noticed you have a manual trans. Has the stalling happened while you have the clutch depressed, IOW the engine is idling? If so, it could be a dirty/bad IAC valve. Again, though, that's just one of many possibilities. Hopefully you can give us more clues and we can help you figure it out.

 

This is considered normal maintenance and could be the cause of your issue:

--------------------------------------------------------------------
The Idle Air Control (IAC) is mounted on the back of the throttle body. (front for 87-90) The valve controls the idle speed of the engine by controlling the amount of air flowing through the air control passage. It consists of a stepper motor that moves a pintle shaped plunger in and out of the air control passage. When the valve plunger is moved in, the air control passage flows more air which raises the idle speed. When the valve plunger is moved out, the air control passage flows less air which lowers the idle speed. Over time and miles, the IAC can get carboned up which can have an adverse affect on idle quality. Cleaning the IAC may restore proper function and is an easy procedure to perform and good preventive maintenance so it is never a bad idea.

CLEANING THE JEEP 4.0 IDLE AIR CONTROL

Remove the air filter cover, associated hoses and the rubber boot that goes from the air filter cover to the throttle body. Remove the IAC with a torx driver (2 bolts; one can be kind of hard to get to)

"Gently" wiggle out the IAC from the throttle body. Gasket on the IAC can be re-used if it is not damaged

Clean the IAC with a spray can of throttle body cleaner; inexpensive and available at any place that sells auto parts. Throttle body cleaner is recommended rather than carburetor cleaner as it is less harsh, safe for throttle body coatings and is best for this task. Use cleaner, a rag and a toothbrush and or Q-Tips. Be gentle; don’t twist or pull on the pintle that protrudes from the IAC as it is fragile and you could damage it.

Thoroughly spray clean and flush where the IAC seats in the throttle body with the same spray cleaner

It is also a good idea to clean the entire throttle body itself, the butterfly valve inside of the throttle body and all associated linkage as long as you have things disassembled

 

no, the check engine light never came on. i cleaned the throttle body with a can of throttle body cleaner and the linkage. let it sit for 30 minutes and then drove it around for about an hour. nothing. idles smoother actually. tried coasting down hill and it did not stall. scratching my head. hopefully that was the cure.

 

Ah, a little bit of maintenance goes a long way.
