If you're going up to 4.5" lift now would be the time to look into an SYE

 

Was planning on that. Got an adj. trac-bar, shackle relocation kit, coil spacers and front shock cheaters. Just wanting to know about the rear and if I even really need to get new shocks.

 

I am stumped on this one. I first start my xj up and after a very short drive it starts this hunting idle upon stopping; while in this hunting mode I get 7 mpg while driving. Black soot and very rich running symptoms out of the tailpipe that also accompanies this hunting mode. The tach will bounce up and down, 300-900 rpms. and it will almost stall when I come to a stop and then jumps up to 900-1000 rpms. once it pops into first gear (I assume, it sorta lurches forward at the last second when stopping, feels like a second to first shift). It'll smooth out a little and then start the hunting idle all over again. Here is where it is confusing. If during this erratic idle I pop the hood, disconnect #4 fuel injector, wait for it to settle out (2 sec), reconnect #4 - it runs perfect until I turn it off the motor, in which I will have to do this same song and dance if I want to drive again. And when I say perfect it does not have an idle problem for 1.5 hrs of stop and go driving. I have swapped out injectors for known good ones and still the same. I had a exhaust manifold leak which I have since addressed and taken care of. It did not help or hurt my issue here. Any suggestions?

 

This might be dumb but have you tried resetting your computer?

 

Not dumb at all. Yes. By letting it sit unhooked for about 4 days too touching the neg and pos terminals for a minute, too many times to count. Either way though it reset the CEL...but it soon came back on. Code from 'the zone' reader says o2, which I changed out as well.

 

Have you ran any fuel cleaner through the whole system? hmmmm

 

Maybe I should start a thread.

I have ran cleaners and also currently running Lucas Fuel treatment. Also seafoamed the $*@t out of her, through intake mani, gas tank and added to oil before oil change. Also I have done most if not all the standard maintenance stuff. Spark plugs, cap, rotor button, wires (plugs were blackened but otherwise properly worn) ....also some non standard. Cleaned or replaced: TPS, IAC, air temp sensor, MAP....basically every sensor on the intake manifold I have checked (voltmeter) cleaned or replaced. I have checked for vac leaks, I didn't find any - although I may have missed a leak (my vents switch from face to defrost if I give her a little giddy-up.)

 

Hmm I would give it a little more time here one of the more experienced guys might have a better answer for you. I am sorry I will see if i can find anything out in the meantime.

 

The rusty's shocks you have are only good up to 4". You will need new shocks

 

Thanks darkfalcon. I have had great success utilizing this forum in pinpointing fixes for my jeep and many of my friends' jeeps, and hope that I have contributed the same. I am a firm believer that 'this isn't the first time this has happened to a jeep' (if only I had a nickel every time I said that) lol

 

Thanks Justin.

 

You are very welcome. The same here!

 

do you happen top have any info on this box located on the underside of the steering column in my 1987 wagoneer Xj.

 

I have a 99 jeep cherokee sport with the 4L fuel injected v6 in it. I left it sitting for a couple days, and now the only way I can get it to start is by giving it gas .But as soon as i let off the gas it dies. I have already replaced the battery,and alternator within the past year and I have full voltage. So please if you have any answers feel free to reply to this message or send me a private message.
