This may be a silly question, but does anyone have any idea how I can identify which brand OEM style motor mount I have? When I bought the truck, I found two of them underneath the passenger seat in unmarked sealed bags. The previous owner has no idea as it's exchanged a few hands in the last 2 years. I've read that some brand OEM styles are much better than others when it comes to longevity. I was contemplating going with some of the brown dogs or similar, but really don't want to deal with the vibrations. I'm not doing any real off-roading anytime soon and want my lady to feel comfortable and happy with the truck (she's a little pissed that it smells like a lawnmower and was loud AF with the exhaust leak, so I'm trying to get her onboard. She DID say that she loved how comfortable the seats were and how smooth it drove, so I don't want to mess with that) I was also thinking about just picking up some NOS Mopar motor mounts, but am having a little trouble finding them and I also don't want to just throw out the motor mounts I have already. If someone could help me identify these mystery motor mounts, that would be awesome. There's no numbers, no labels, nothing... Just a relatively unique shape that I'm struggling to find in other motor mounts. I know this is a shot in the dark, but you guys are awesome so it's worth a shot!

Hey all, I hope this is the correct section for this sort of question. I'm trying to identify what these bucket seats are called and what model comanche/cherokee they are from? They look to be original, but I've only found a few other examples of these seats in pictures online. Although I'm doubtful I'll be able to source the material because it's so unique, I love the design of these seats and would love to have these restored to their original look. Is there any chance of me getting these restored?

I ended up pulling the exhaust and intake manifold last night... I think I found the source of my $#!&ty O2 readings and running rich. I’m dropping it off at an exhaust shop to get it welded up today and will put everything back together. What’s the consensus on flex pipe to help take the stress off the manifold? Would I have the flex pipe installed on the Downpipe? I managed to take a couple videos of the REM while driving and just like 87MJTIM said, as soon as it goes into closed loop the ST fuel trim starts just dropping to 0 until it errors out and goes back to open loop. This REM is such a @#$%ing amazing little device. NickInTimeDesign, you are a legend 🙇‍♂️ Best $ I’ve spent as it already saved me hours of headaches and wondering. I’m going to do the motor mounts while I have the exhaust off. I was thinking about getting aftermarket mounts because I heard OEM ones fail quickly, but the previous owner already bought new OEM mounts and never installed them. I’ve heard some horror stories about vibration from some aftermarket motor mounts so I’m thinking of just reinforcing the gaps in the stock motor mounts with urethane window weld... but I know that’ll lead to more vibrations too. I’m not doing any off roading in her anytime soon and I want my lady to feel comfortable in the MJ with me. Thanks guys! I’ll update the thread once everything is back together.

Wow, thanks for all the great feedback guys. Let's see where I'm at and what's been done so far 1 - grounds have been refreshed throughout. I'm going to be adding in the additional two grounding points recommended by Cruiser this weekend 2 - C101, I opened this up and cleaned this out a bit but decided I'm going to eliminate the C101 before I put too much effort into cleaning. 3 - I've refreshed the connectors for about 40% of the engine bay so far, starting on the drivers side including relays. 4 - Haven't done anything with Coil/ICM but will bang that out this weekend as well 5 - Haven't checked the sensor grounds yet but I plan on doing tip number 6 as well. Thanks, but I've double checked all vacuum lines. the previous owner had replaced all vacuum lines in the last few years. Intake manifold bolts i'm doing tonight! I have a feeling this guy may be a culprit. This sounds spot on. I dove into the fuel injection manual and holy $#!& is it thorough. It does a great job with helping me understand all the components and their relation. I had the biggest smile on my face reading through it. I actually just discovered the REM last night and ordered one immediately! Seems like an invaluable little tool. I've looked through this site before and it looks great! I went out an picked up a multimeter last week to help with diagnostics (moved back from Indonesia last year and have been repopulating my tools as I had to sell everything when we moved out there). Just been so busy with work and the new home that I haven't been able to jump in!

Hey all, Wondering if anyone might be able to help diagnose what’s going on here. When idling, the RPMs stay around 800 and it sounds alright but then every 15 seconds or so the RPMs drop down to less than 500 for a few seconds and it sounds like it’ll stall then it goes back to 800. Other times, at the same 15 second interval, the RPMs will jump up to around 1100 for a few seconds before dropping back down. My sig should have details on the MJ, but it looks like the last owner has put in the 4 port hole fuel injectors and had just replaced the IAC. she smells like she’s running a bit rich, but I’m not sure what these are supposed to smell like. Smells like a go-kart or lawn mower. Also, today I discovered that the cat had been hollowed out so that could contribute to some of the smell... I’ve just picked her up a couple weeks ago and am just diving in. I’ve attached the link to a couple videos. I haven’t determined any difference in scenarios between idle dip or idle surge. My first week I thought it surged more but this week it’s been dipping more. Still doing both. idle dip http://www.youtube.com/shorts/oC1tDuUP410 idle surge http://www.youtube.com/shorts/Yraf39w-GM8

Hey all, I just picked up my first jeep and love it already! Here's the limited info that I know about it. 1987 Jeep Comanche Pioneer 4x4, 4.0L, 5 speed manual, 6ft bed Build Date - Unknown. The sticker on the door is destroyed Current Location - Durham, North Carolina Status - Running strong and on the road Notes - Purple exterior(used to be blue), blue interior, blue dashboard, blue leather bucket seats and wooden dash trim. Floor shift. Pretty much bone stock aside from a 2 inch lift. Current Owner - Phil W (me) Just crossed over to 147k miles. I'm really loving the forum and the wealth of information. I have so much more to learn about these guys! Current project is trying to sort out a running rich and rough/sporadic idle issue... I'm working through cruisers list, but it seems like the guy before me was on top of it. TB is cleaned, grounds have been refreshed at a few places. I know the previous owner has done some work, as a lot of things have been replaced, but I'm trying to figure out what's stock and what's been replaced/modified. I'm noticing some weird wiring on the passenger side of the engine bay that I was planning on asking about on the forums
