This is good to know info. I was just thinking about this today as I was staring at the dash waiting for my wife to get off work. Thanks for posting up guys!

Looks great. What speakers did you get? Ya they say Wednesday is going to bring nasty weather again. I drove our Comanche to work today. I dunno what it is about these little trucks I just enjoy driving them.

Just to follow up the problem was a combination of things but primarly it was dirty leaky injectors.

The round plastic ball you mentioned is for the climate control system and is more or less irrelevant to your problem. Replace the IAC and your problem will be solved. Thanks. I did some more work on it yesterday morning and unplugged the IAC. It would idle barley for a few seconds then peter out. I had a IAC i had gutted awhile bac for diagnostic purposes so I installed that and it idled but was high, as expected, but it was smooth and consistent so I have a new IAC on the way. Thank for the help

Ummm I am going to guess " Taken" and I like the radio. What are your plans for finishing up the install? Right now our Comanche has a Vintage Kenwood Tape player. IT works but not the FM/AM which will drive me crazy once we start driving it more. But for now When i drive it I listen to Alabama tape I found in the glove box. lol

Little update. I finally did get the fuel line on and even used the old clip. I put the orings and spacer in the line as they described in the manual. I would go to put it on the fuel rail and it would seem like it just would not go far enough for the retainer to catch. SO i thought what the heck I would take the outer oring off and see if it would click on. I could check to see if it leaked after the fact. So thats what I did and it seated on the fuel rail inlet and does't leak prob solved. So i started the truck and checked for leaks and then drove it a couple miles the next day. The engine still shuttered and was low on power and would not idle. So i parked it. I checked fuel pressure, it was good, i checked vac pressure with the throttle slightly open to keep the truck running(used a brick on the gas peddle) and it was steady at 25#. When i pulled a vac line to check the vac pressure i noticed the truck kinda surged and took a breath and idled....not smooth but it did stay running on it own with out the brick. I traced the vac line down and it lead to the black round ball vac resevoir behind the front bumper. I took the resvoir off and checked it out. Seemed to have alittle water in it. Well night before last I couldnt sleep very good so I went down stairs and put the Vac resevoir back on the truck and I went ahead and put the new spark plug wires on. While i was changing out the wires I found one of the old wires was not even on the plug! So its been running on 5 cylinders so that would explain the engine shutter and low power, even with the new injectors. So this morning after I fed the cows and carried in some firewood I decided to mess with the truck abit. I pulled the IAC plugin and that helped the idle alittle bit. It will idle for a min then peter out. I had a gutted IAC from when I was fooling with it before. I put the gutted IAC in and fired the truck up. It idled very high as expected it but it did idle smoothly. I think it needs a new IAC. Its snowing here! 3+ inches and still coming down.

how did these fit for you Jeep Driver? I pulled the round ball vac resevoir off the other day and i pulled buack the rubber flap back to get to it the inner fender began to disinnegrate. If you were happy with these I will order me a pair. The price certainly is right.

I broke the same line when changing my injectors. I used a piece of rubber Vac line to splice the pastic line back together for a quick fix. And yes that is clean looking engine bay.

I use Valvoline VR1 oil for my AMC 360. It has the Zinc content as well. The correct oil is critical when your talking about flat tappet cams these days. Oil is not designed with them in mind anymore.

I thought the same thing. I have had the IAC out and cleaned it tho (it looked brand new) but it could be stuck shut or malfunctioning somehow. I mentioned above that I have not cleaned the TB.

Nope, I did unplug the TPS tho while i was cleaning plugins. Are u suppose to recalibrate it if you unplug,even it with the engine off?

Looks good nice work! You need a grill? I have one as well as bezels but i see you have those already. Subed

I have changed fuel filter, injectors, cap and rotor, spark plugs, ECM, and CPS, check out my thread "Em's MJ" but long story short the truck won't idle. I had a brick on the gas pedal to keep the truck running so I could check vac pressure and when i pulled the vac line on the intake the truck surged. I took the brick off the gas pedal and it idles. I traced the vac line to the front of the engine to a round plastic ball just behind the front bumper. Another small plastic line attached to it as well. I took the ball off and it has water in it, I can here it slosh around in it. I blew air through the vac hose and its clear. Any idea what is going on here? Generally when you unplug a vac line an engine will run rough and shake quite, the opposite here. BTW Vacuum was rock solid at 25# with throttle slightly open. Fuel pressure is with in spec. I would post pics but for some reason when i right click the paste option is not working......

All the parts are in for the injectors R&R but its to cold and nasty out to do anything!

Well today I was able to order a set of Bosch 4 nozzle re manufactured injectors. $89.99 off fleabay! 3 year warrenty from the day they are delivered. I also ordered the new fuel line quick release thingies for the fuel supply and return line. I ordered those from Morris 4x4. I also ordered a new fuel pressure regulator from local parts store. I am also going to install a new fuel filter, that will be the third one. Once all these parts come in within the next 7 days I will go about installing them. Any of you have suggestions, tips or tricks for this procedure? I think it's pretty straight forward but doesn't hurt to ask those who have gone before me. Suffice to say they should be easier then replacing the injectors on my Ford Super Dooty 6.0. And lots cheaper!

Thank you! Its coming along. Well my heep has been taking up alot of my time and money so not much has happened to the MJ lately. I did track down two more used tires and put on some ole hub caps I had. BAM! Classy :D I am working on selling my tow rig and my wife's car so we can buy a lower milage SUV for if we have children soon. :help: If both the car and truck sell the MJ will be at the top of the list for repairs and upgrades so we can have a second reliable 4x4 DD. :banana:

Sooooo the blown out muffler was getting annoying so this morning I went and had a Magnaflow muffler put on the Comanche. It was only $20 more then one like what was on it and the Magnaflow is stainless!. The cat is still on it but muffler guy told me it had been gutted. Its not loud at all really only when you hammer on it and even then in the cab it doesn't have a drone of anything. I didn't do a rear dump, it had a basically new tailpipe over the rear axle that came out behind the rear wheel so i just reused that. It is sitting at half a tank of gas/seafoam mix right now. I think I am going to dump another can in just for good measure! Other then this no exciting news to report. I am going to focus on finishing the EFI of my AMC360 in my cj5 for a few days/weeks. Speaking of here is a pic of the heep.

I like the bobbed look plus you get the longer wheelbase of the long bed chassis. Well I drove the truck all day yesterday and found to used tires for it, just before one of the rear tires was fixxing to let loose. Today I replaced the broken passenger side glass and the window regulator. It wasn't to bad but took longer then I planed. Getting the weather striping and such back in correct is tedious. After I got it together I drove to a friends house to pickup his mig welder to borrow. On the way home I stopped by sonic. As I was pulling into the stall to order the truck died and it didn't start right back. There for abit I was worried I was going to be at sonic for the remainder of the evening. I cranked and cranked and mashed the gas and let it loose and mashed it again, finally it roared to life. Then I hammered down to get home. I have ran a half tank of gas with seam foam through with little improvement. It still will not idle and it has the shakes when I am going down the road and the truck shifts into high gear. I am going to start looking for new injectors. I have some 19# Ford Mustang injectors but they would need orings at the very least. I would feel better sending them off for rebuild but that's $108 from the one place I have found online. I can buy some reman 746 injectors for $89.99 on eBay all day long. The 746 injectors have the 4 way nozzle and my older 5.0 injectors do not. Sooooo I am thinking 746! But before I drive the truck much more I will be replacing injectors. I will say that I love driving this little truck around. It moves down the road easy and steers straight.

Thank you I will remember that. Ya I was in a hurry and against my better judgement I used the pliers. Oh well I guess i will replace window glass now and the window wipe seal while i am at it.

The first time I was introduced to seafoam was with ATV's. It will sure clean up a carb. I am hoping it will do the same for my injectors. If not it maybe time for a 746 injector upgrade. BTW BlackBeast is your bed bobbed? In other news my wife was riding in the truck with me while driving around on the farm. She rolled the passenger window down and then went to roll it back up. The crank handle just made a noise that sounds like the regulator gear slipping. We got back to the house and it was dark. She said just let it wait and work on it in the daylight.....but of course i knew better. I grabbed a pair of small needle nose pliers and lightly grabbed ahold of the top of the window and thought I would assist the window up while cranking the window handle...light pressure was applied and crack. The window broke. AWESOME! The wife enjoyed the I told you so but other than that she was not impressed. So i guess will hit up the salvage yard for a replacement glass. I am getting insurance on the truck today. Might drive it around on some short work errands tomorrow. I will be sure to have a spare tire and won't break any speed records with the not so good tires that are on it. Atleast the fronts look better then the rears. TBC

Picked up the plugs wires today and a bottle of this! I think the plugs wires can wait so I poored this whole bottle of sea foam in , I figured it had about 6 gallons of fuel in the tank. I went to start the truck and with alittle throttle it fired up. I went and fed the cows a round bale of hay and everytime I stoped the truck to open gates and such it died but started back up with alittle throttle. I got brave and drove the truck all the way down the drive way which is a mile long and then I drove it down the hwy about 2 miles. When I got back to the driveway the truck did idle when I took my foot off the gas but by the time I made it back to the house it would not idle. I think I am on the right track and what this thing really needs is to be drove! That's gonna have to wait for new tires tho because the tires that are on it are dry rotted and not road worthy......sigh. I may see what the local tire place has for used tires because I hate to put new tires on it yet because I am thinking I will be running 31's once the truck is 4x4. If driving It doesn't clear it up completly it may need new injectors.

I read some of progambos post over on cherokee forum and I think what I am dealing with here is a severe case of dirty, leaky injectors.

Haha I own a VW also so I learned to be persistence working on that aggravation. Lol I bought new plugs they had to order plug wires. i came home pulled all the plugs turned the engine over w/o plugs then set the gap on the plugs and installed them. cranked it over and nothing. Then I busied myself with other things and installed the driveshaft. then i tried to start it again. It kinda started to hit alittle so i held the throttle open and it came even closer to starting. I cranked on it some and let the starter rest. Then tried again and finally it caught up and started. it bellowed white smoke for a min. i drove it around abit but it never got to where it would idle. It would restart if i feathered the throttle. Thoughts?
