Thang, you mean.

SOMETHING has to be leaking power or preventing the battery from charging. Most likely a short in the wiring or a bad ground. Go though each area they touched and check that all the grounds and connections are tight and no metal wiring is touching the body on power wires. Also get the battery LOAD TESTED at your local auto patts store.

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

i still need to do this lol havent had any sputtering since the last time knock on wood lol

Thang. Correction.

The fact that she hasn't posted her location goes unnoticed by all. lol

dorothygriggs

we have no clue exactly what they touched is one proplem....but we are still problem solving forsure. hope we get it figured out soon or I am going to go crazy.

Lowrange2

You fixed the battery terminals yet?

Are shops outrageously priced in Indiana? Seems a shop could have diagnosed the problem for less than you have in it by now...

dorothygriggs

yes that was the very 1st thing we did. still didnt start. took out alternator and battery took to auto zone. they barged battery up, it was a little low. tested alternator and it tested perrfect so tehy said its the computer, ok so got that and still didnt start. unhooked the amp wire from the battery, truck started. ran for a week and dead again, so replaced alternator and still won't start

Lowrange2

You're throwing parts at it. Don't do that anymore.

The computer isn't killing the Jeep... that's the first thing idiot autoparts store people suggest. You know what it takes to get hired a place like that? They have to know what a car is. That's about it. Make them take the computer back...

Diagnose the problem before you buy anymore parts. Or find someone who can.

If you just had stereo/amp installed. I would be looking for positive cable touching somewhere. Amp power wire first.

dorothygriggs

that's what we thought too, ALL stereo equip has been removed, amp, speakers and the deck itself, power wire for amp has also been removed.

MoparNJeep

Well everything worked till key was turned to start position. So I would look at starter connections. If they are touching it will do what you are describing. If that is not it, a loose connection could be at starter cylinoid which is next to battery where people usually hook up power for amps.

It's pouring down with rain - my XJ is leaking!

I've got the overhead console in my '98, and water is dripping from the on-board computer screen in it, landing in the cup holders.
Water is also coming down the A-pillar, all the way down in front of the door, and collecting on the floorboard underneath my carpet and mat on the passenger (RHD XJ) side.

I guess this could be the roof rack or the windshield, but which is more likely? Is there anywhere else it could be coming in to cause this?
There doesn't really look to be any rust under the windshield weatherstripping.
