  1. Hey people, As some of you way know of my build thread "Wendy". Well I have a 1988 Comanche with a 2.5l inline 4 (tbi) and a 1988 Cherokee with a renix 4.0l/aw4/np242 drivetrain. I tried to start the Cherokee but it was just cranking (not turning over) sounded like it had a rod knock and some smoke was coming out of the dipstick https://www.youtube.com/watch?v=keTuB2oHwsY (wasn't sure how to make the video thumbnail appear) But I'm not 100% sure what it is. It sounds like knocking. Because of this, ​ was ​going to keep the 2.5l in the Comanche, and just make the best of it. My real question is, would I be able to "fix" the 4.0l for around or less than $700? Because if it is more than that I might as well swap in an ax5 behind the 2.5 and just save for the time being
  2. Hello fellas Well, i've just acquired my Comanche 1988 4.0L, 6 cyl, and looking behind the hood i saw some unusual things. One of them is that some hoses are not plugged in, and other components. (I don't know a lot about mechanics, but i try to do my best) I saw this component called "Charcoal Cannister" And yes, is not plugged in. Also, i saw that the engine have 2 hoses, one in front, and another one in the back (near the cabin i mean), the hose nearest to the cabin is not plugged on anything, in fact the seal broke and is uncovered that part of the engine. Someone can explain me how to reconnect this? Because i was looking for info and not having connected the cannister can affect the consumption of gas and the emissions can be higher. Please, help
  3. Hey all, new to the forum, been using this and jeepforum for the past 2 months to keep my MJ up and running. Quick history on the MJ then I'll give ya the dirty dirty: Swapped for the MJ (4x4, 4.0L, Big Ton, with 5-spd) about the end of August down in NOLA. Exhaust manifold wasn't connected, but otherwise it ran great. Drove around town like a bandit then left a week later to Alanta with no issues other than gassing myself in slow traffic (also, possible hearing loss). In Atlanta, bought nuts and reconnected exhaust. Much quieter, ran good for another tank of gas (300 miles maybe less) started idling rough. Pulled plugs (they were shot, maybe even original to the jeep). Replaced with Autolite 985 copper core (gapped to .035" I'm pretty sure). Fixed idle issue. Loaded up and headed back to NOLA. Left mid afternoon, got a hesitation or two along the way, could have been a bump in the road. I get about to the La. state line (about 11pm) and the truck starts misfiring and surging erratically. Hold the throttle and try to cruise at any speed/gear/rpm and it bucks and fights. Under hard acceleration the problem is there but much less pronounced. Let off the throttle and the issue seems to go away (truck isn't shaking anymore, hard to tell over hwy noise). No CEL at any time. Limp into NOLA and over next 3 weeks: Replaced Fuel filter- no change Tested fuel rail pressure and flow rate- ~31psi and 39psi with regulator connected/disconnected. With return pinched off flowing close to 2l/min (filled 500ml bottle in 13 seconds). Pulled spark plug wires and checked for resistance...all were similar with longer wires slightly higher than shorter wires. Cleaned ends and reattached (all done one at a time then double checked for order) - no change in symptoms Pulled old O2 sensor and bench tested. Readings very erratic. Order new Standard SG1829, bench tested it to compare readings. New one cycles as expected from .1-1.0A in flame. Installed new O2 sensor and problem appears to be fixed. Test drives, no bucking, no skipping. Next day leave NOLA around 4pm, drives great for first 150 miles. Pouring rain, temps drop and from around Lake Charles to Victoria, Texas the misfires are as bad as ever. Pulled over several times and disconnected/reconnected O2 sensor trying to get the ECU to run the motor rich, used ether to locate at least one vacuum leak (repaired with electrical tape), tried plugging vacuum lines, looked for spark leaks, wiggled wires and lines, dumped in a bottle of B12 Chemtool and 89 Octane out of desperation, nothing. If driven at high rpm the misfire is dealable but anything below 2000 rpm I'm afraid I'm going to blow the bottom end of the motor out unless I'm accelerating WOT. Then, after taking a nap in Victoria I wake up this morning, fight the misfire for about an hour and after the sun comes out and it's 84 outside, the truck drives with no issues. I can't get it to misfire, even by lugging the engine under 1200 rpm. I've got a cap/rotor/wire set on order, bought PCV(CCV, little plastic elbow thingys) to fix my blow by, and some new vacuum lines just as maintenance items on this thing. If these don't fix it, does anyone else have any other ideas? I've read about a coolant temp sensor maybe? The fact that it seems to drive ok in 80*F and hotter has me a little confused. Posting this on two separate forums....I'm not looking to parts swap and guess. If you can give me an idea and a possible troubleshooting (or hell steps even!) I would rather do that than throw money away.
  4. I am looking for a 3/4 or full guage cluster for my 1989 MJ with the 4.0L and automatic transmission. Let me know what you have and price shipped to 72687. Thanks.
  5. I have a bad oil leak. I jumped the gun and I replaced my rms. In the process of doing that I power washed the engine. Upon driving the jeep after I now realize it is leaking oil from the head gasket on passenger side. Any advice? I guess I will pull the head and check the head for cracks/ straightness and replace the head gasket. Do I need to replace head studs as well? Engine is a 4.0 that just turned over 170k.
  6. Did a search but nothing came up... I've really only worked on or owned long enough to know 2.5l 86s (4x4 ax4/ax5) before I got myself an 87 4.0l. automatic 4x4...... Now I am totally lost. I noticed the rear driveshaft on my 86s is almost twice as thick as the 87's. What othe differnces are there between them? We found one of three vacuum lines that seem to go to the t-body/intake-manifold via a U shaped hard plastic hose isnt connected to anything and I don't know whats missing here as it is definitely sucking (and hissing). The other lines are attached. Does anyone have a list of what lines/components are supposed to be attached to the t-body vacuums? I followed one larger white hose from the junction clip that is just infront of the tbody to the airbox and engine, the other is a smaller black hose that snakes under the air box - brake booster? Which gauge cluster is supposed to be in an 87? The blue or the black/red? Its obvious someone swapped them at one point since the odometer is meddled with and the temp/oil dials don't work. Also the scratches from the tinsnips used to cut out the gear selector panel are obvious. Good effort though. Some genious removed the CAT - is it necessary for function? I am e-test exempt and have no intentions of driving to california. What is the function of the transmission button on the dash that says power/comfort?
  7. Ford E6TE A2B Injectors. From my research I believe these to be 19# Mustang Injectors. Good replacement for 4.0L stock injectors. These will probably need a rebuild. I bought them to install on a ford inline six cylinder years ago That never happened and they have been sitting in a box on the shelf for 12 years. $30. Would be shipped from Harrison, AR 72601.
  8. It's breaking my heart, but I'm looking for a new home for my 1988 Comanche Pioneer Shortbed Pickup.

On the exterior, rubber molding (have most) and original vinyl graphics have been removed. Sanding of the paint had started, so some of the body is in primer. Some minimal light surface rust in those areas. One dented area on the right rear bed edge where my brilliant brother dropped an oak branch. Good Michelin Tires and Stock Aluminum Wheels Have a few boxes of new parts (about $600) that will be included with the truck: Door Lock Cylinders (NIB) Custom Aluminum Expansion Tank (NIB) was 162.48 with shipping New Set of Door Rubber Seals Assorted Sensors : Bosch O2 AC Delco Idle Air Control Valve Standard Engine Coolant Temperature Sender Standard Coolant Temperature Sensor Heater Valve 4 Seasons Side Markers (NIB) Metal and Silicone Head Gasket - hasn't needed it yet Large Piece of Tan Headliner Fabric (From Team Cherokee I think) 2 Bumper Guards 2 NAPA 4G Battery Cables There may be more parts, books & manuals up in my garage attic, I will include everything I can find.

I'm looking for $1400 which includes all the new parts. I am located in Revere Pa which is about an hour or so northwest of Philadelphia and 20 minutes south of Easton.
