That's all I found for exhaust diagnosis. It kind of works in reverse so you have to know what you need to fix. With the rough idle there is so many things it could be but I'll keep looking. I'm going through electrical now

1, 2, 3, 4, 5 - are checked, all fine

8, 9, 10 - also checked and double checked, fine
11 - How can I make sure the torque converter is ok? Stall test shows 2400rpm

Stil having trouble from "N" to "D", but from "N" to "R" is ok..

Hello everyone. I haven't been on in a few years due to a "very" messy divorce and hence my 1996 ZJ has suffered some neglect. I have a few issues that need attention soon but aren't despite yet.

1..Control arm bushings are rusting but rubber is in good condition. Was going to replace all upper and lower along with the sway arm bushings. So needless to say I decided why not lift it some. Now I'm not a big fan of off road driving so I don't need anything extreme. Any suggestions on around a 3" lift that has all new springs at a fair price. Also do any of them make a stiffer spring. I really dislike the top heavy feeling my jeep has compared to my 4x4 Chevy. I'm not one for half assing anything. That usually costs me a lot more cash than I'd like. Lol

2..I have a low whining while turning at higher speeds like off ramps when the Jeep leans a little. I'm suspecting the bearing hubs are going bad. Passenger side has very slight movement when I have the wheel off the ground. If this is the problem what are a good brand to buy?

3..I need new head lights for it due to clouding. I'm getting sick of polishing them up all the time and since I work nights it's a must to see well. I was wanting to get smoked lights all around since I have a pure black ZJ and no chrome. What are some good brands and dealers?

Last I have something I think you should add to the list here because it happened to me and caused a **** ton off issues.
"PASSENGER SIDE FLOOR BOARD FLOODING"
I thought I had a leaking windshield however it turned out that the water drain was clogged and allowed water to overflow the heater core intake. It soaked the fuse panel and shorted out quite a few relays. Plus made my cab smell of mold. It took several days to dry all the flooring out "once" I removed it from the vehicle. It's quite heavy when soaked to. Lol. So needless to say it was a stupid and easily avoided issues that was a massive pain. Check those water ways below the windshield for leafs or other buildup.

Fourth, swap out the Governor Pressure Sensor and Shift Solenoid. These sensors commonly go bad and can cause problems that will make you think you need a transmission rebuild. They are easily accessible by dropping the pan. I replaced my Solenoid with the upgraded Borg Warner unit.

Fifth, completely replace the TV/Kickdown cable. I have read on the forum that people have done this with success. It is a few feet long and can stretch out over time. Also check where it connects to the transmission as the connects can come loose/become disconnected.
Do you have links or part numbers for these? I get a lot of random results for these from OReily's etc.

Hi everybody,

46re
1. having harsh switching from "N" to "D"
2. kick-down while running on 4-range firstly switches to "3" and then immediately to "2"

I did full pressure test as descrybed here
http://www.cumminsforum.com/forum/91...tml#post258206

everything is ok, except one
look,
REAR SERVO has
on "1" range 60-92psi
on "R" 160-270psi

ACCU PORT and FRONT SERVO have quite the same values

GOVERNOR PORT
on "D" range it grows from 0 to 20psi, we did it on the hoist, speed was from 0 to ~30mph

and now
pressure at overdrive port is constant, it is 55psi at any speed (I did at the moment about 90 miles and pressure still the same)

As I understand at this point it also should grows according to speed

Any ideas?

Thank you

Hi guys, my 98 zj 4.0L broke the valve spring last year, so I took off all the engine head and fix this problem and clean all the head 0,05mm. now my problem is a stalling in low range, around 2000 and 2,500 rpm. Could be the valves or the head????

#17) whining/groaning on accelerate/decelerate

This happened to me. I bought the jeep (95 ZJ) and it whined above 10mph like you're manually rolling a remote control car. Well it lasted maybe a month and my transfer case self destructed on the interstate. Did the 242 swap and the noise is gone. Might add this as something to check, because 2 quarts of atf and or a new chain would have saved me a lot of time and money.

And a couple months later... Here's the seized rear wiper motor write-up for the link on the 1st page which doesn't work.
