As of the last few days when I fire up my 87 4.0 it acts like its not firing in one or more cylinders for the first few seconds of running,after a few seconds it clears up and runs fine. It seems the longer it sits as in a couple days the more noticable it is. Im thinking an injector(s) is...

I bought a 87 4.0 with 110K on the clock,drove it home about 120 miles with about 40 psi pressure on probably a 2 year old oil change of who knows what oil, changed the oil with a Penzoil filter(dont say it, I know) and 10/30 oil. fired it up and the first 50 miles or so the pressure at speeds...

This seems odd but Ive put about 500 miles since getting the 87/4.0 and have changed/checked the oil about 5 times after it sat overnight and its always right on the money. Today I fired it up to move into the shop and decided to check it before I head out and its a quart low after it sat for...

I did a search and didnt really see what I need. I recently picked up a 87 4.0 auto. This is my 4th XJ, one 93 one 95 and one 85 with a 2.8. I think this is the only renix one then which Im not familiar with? Couple questions. It cranks longer than the others to start, 5 seconds maybe then...

My 87 must be missing something at the top of the pedal assembly where the cable fits in a fork like slot, its been wired so the cable cant be slipped up and out of the groove? whats missing here or is the cable not supposed to come out?

I posted about running temps on my newly aquired 87 4.0, the stock guage as my other early XJ seemed to run to cool to be right. Anyhow this is after a 40 mile drive, the stock guage,new 195 thermo and clean system with 50/50 mix of coolant,it runs just above the middle mark between the 100...

Im on XJ #4, its an 87,4.0,auto,selectrac,D44 rear/D30 front,3.55 gears, I will not run bigger than 30`s for now until I regear (if ever)if ever as I need towing power to haul a fishing boat at high elevations and some economy still. I will use it for running aorund, 500 mile fishing trips to...

Best I recall in the 2 newer XJ`s Ive had the temp guage ran pretty close to 200/205ish with a 195 thermo. I just serviced the cooling system in this 87 and a new 195 thermo but the guage still shows half way between 210 and 100 which looks like 170 maybe. I think my 85`s was off also but cant...

I searched but everything I read was related to 90+ vehicles. Can someone point me in the direction on an 87 to the aux fan relay or fuses. Jumper it and it runs, no worky with either the AC hot engine. Thank You.

The 87 auto/4.0 /selectatrac/ I just picked up has a switch in the dash for power or comfort, the little light on the switch dosent i,,uminate when put in power mode and I cant really tell any difference in shift patterns, is there a noticable diff or is the switch bad or? any suggestions. It is...

Ive addmittedly never owned a 4.0 jeep with the closed system until a few days ago on my new to me 87. My cap on the recovery tank always seems to be hissing when it pressurized or running. I dont imagine this is correct on this the way its supposed to be? Also I have yet to find an A/P store...

Whats the thought on V/C gasket R&R for an 87 4.0 ? Cork, a small bead of RTV or a rubber one which I was told was $58 at Autozone. Insane I thought for that , cork is a mixed bag due to cracking after drying out, the PO did a mess of a job with RTV and it still leaks pretty bad, Dosent surprise...

Been gone for some time,nice to have a XJ again,makes #4. I sold the TJ and picked up a clean 87 XJ with 110K and a D44 rear diff, Im weeding out a few things, first is the auxilary fan supposed to come on reguardless of engine temp when the AC is turned on? #2 I recall reading somewhere a D44...

Fug, I sold my XJ some months ago and bought a TJ. Biggest friking mistake I ever made, what a POS this thing is in comparison. I dont understand? same name, the rest is beyond my understanding. In 60 K miles Ive had more repairs on one TJ than all XJ`s put together and all with near 200K miles...

Just wanted to say thanks for all the info Ive obtained here, particulary regarding the 0331 head syndrome. Ive looked at 5 jeeps so far, all 99 to 01, 3 TJ,s and 2 XJ,s all with the 0331 heads and about 95 to 105K on em. I passed on em all to avoid the hassles. Thanks

95, 4 door sport,auto 4wd,PW,Tilt,PL,cruise,No air, 197K,Budget lift,good tires/brakes, has been problemless DD for 2 years, smogged 3-4 months ago and new tags,hitch,trans cooler, mice damaged wiring to speed control, repaired it but engine light still on and no speedo/odo/CC operation. Im...

I posted that my wiring was chew up by mice from the speed control on the TC up a ways on the pig tail, I repaired it and tried 2 different speed comtrollers and still no speedo,cruise control and the check engine light comes on after about 5 miles. Does anyone have a factory manual for a 95 4.0...

I need the 3 wire harness for the speed control from the Transfer case to the main above the oil filter area. This is for a 95,4.0,4x4,with cruise and AW4 auto. Thank you.

After about 5 minutes of driving this am the check engine light came on and the speedo and odo died. Any idea where to start? its a 95,4.0,4x4,auto. Thank you.

I found some folks with 98 2 door,5 speed 4.0 XJ4x4 that they brought in from Canada. Is there any differences in Canadian models? Also seems 1/2 the 97+ XJ`s I look at the air dosent work. Is there something common that goes out? Id sure like to have working air in the DD. Thanks
