Bought a 97 XJ SE with a blown motor a while back. Got a nice deal on a replacement motor and thinking about doing a few mods, but I'm not sure what year it's from, is there any way to look at the block and tell? Thanks in advance.

 

Block codes are on the drivers side under the intake.

 

Okay, yesterday I got on the freeway and when I was accelerating to about 60-65mph my xj felt like someone (the night before) had put a drive shaft limiter on it. The drivetrain noise increased, not a grinding or clanking sound, just a louder whirring noise as if there was something binding somewhere. If I stayed below 60mph there was no sound or resistance. I shifted to full-time 4wd and the sound and resistance went away until I reached 75mph. Around town at lower speeds everything seems normal. I changed the tranny and t-case fluids (no debris in old fluid). The rear diff was a little low but after topping off the same thing happened. Any ideas? Stock 91 XJ limited 4.0L, AW4, NP242, D35 rear diff,

 

What gear were you in before? 2H for 4 Part Time?

 

Did you plug or reroute the vacuum lines for the ducts?

 

This is a little off the wall, but I put a new radio in my 2000 xj the other day, and now when the volume is low, the radio makes a quiet high pitch noise that gets louder when you give it gas, I am positive that it is the radio making the noise and not anything else. Anybody know what's up?

Here's an install write I found up w/pics. http://www.myjeepxj.com/cherokee-rep...mission-cooler

 

I was in 2WD. It's all stock, no lift or rerouting of anything. Also when I shifted from OD to Neutral the sound and resistance went away. I could coast on a decline to any speed with no issues.

 

Google radio interference. It's gonna have to do with the upgraded stereo input and out put for signal and the electronics in your engine ie coil and plug wires or alt.

 

Thanks man.

 

Is it a new, "new" radio? Typically all new radios have a built-in capacitor, which eliminates that noise you're hearing. What you're hearing is a type of interference which actually comes from your alternator spinning faster as your engine accelerates.

 

This. Yes. Beat me to it, with a better explanation. Haha

 

Also look at your plug wires. Most say interference free. If not its a good place to start lol

 

'98 Cherokee Sport 5 speed v6 4.0

recently had the wires ripped out of my o2 sensor after the cat converter. a short time after i replaced it with a new o2 sensor (check engine light still on, never reset), it started bucking in lower gears. it feels like a fuel problem, but it idles fine.

i've tried to do a self-test to see what codes come up, not sure if i did it right. when i press the trip/odometer button, turn the key "on" and let go of the button, "2.3" shows up for a second (different from my tripometer reading).

any ideas on the problem? or a way to bring up the p-codes that i haven't tried?

thanks.

 

I just mounted my surco rack onto my xj with gutter mounts and I was wondering how it would be possible for me to mount a kayak up to without breaking anything. I have gutter mounts and while it feels sturdy I don't really want to risk anything. I haven't bought a kayak yet because I don't know if i can carry it up there for sure.


Any help would be appreciated. Thanks
