I definitely would like to do a 4wd swap. But mainly this one has interior parts that would be nice!

I’m considering it as a parts Jeep for my Comanche. Looking for more info on it. I know it’s 1991+ since it’s an HO.

IMG_1728.mov Here’s a short video at idle.

I’m trying to solve a rich-at-idle condition with my 2.5 TBI. I’m still learning my way around this system. My question: is it normal for the injector itself to be noisy? It makes a chattering/rattling sound that I can hear from the cab while sitting at idle. I have confirmed that the sound is indeed coming from the injector, or somewhere very near it within the throttle body.

Found on a back road near my town. Last registered in 2001.

Thanks for the kind words everyone! I feel blessed to own it, and I’m enjoying learning from all of you. It’s neat to be featured this month specifically, because today is my Comanche’s build day.

I’m starting to figure out peoples relative ages from this thread

I drove a 2003 Chevy Tracker throughout high school. Then I took it to college for one semester before selling it. Back then I had dreams of lifting it 😂

@garyweb3 where are you located? I’m in eastern Ohio.

I’m looking for parts to add power steering to my 87 2.5. Specifically a pump, reservoir, and steering box. I’m open either an XJ/MJ box or ZJ box.

I’m running 30” tires with 3.55 gears. Runs around flat ground just fine, struggles a little on the hills, but not unbearable for me. However, I don’t have overdrive.

From that plug, it looks like you’re running rich.

Does anyone here have experience or opinions about the 2.5 to 2.8 Stroker that Titan makes? It seems like a neat idea, but I’m sure there’s a list of pros and cons…

Looks clean, but wow… that’s a lot of $$$

Replaced the front brakes this weekend. I found @WAEMID IV’s video helpful, especially with ordering the right parts. I totally spaced out and forgot to order a set of pads. Thankfully the previously installed pads still had a lot of life left. No I can use my brakes without shaking the truck apart!

Who widened your Rallye wheels? I vote Vector.

My truck came from Washington near Spokane

@ROCKNMUD I saw the keychain in one of the pictures in the marketplace add, and I hoped they would send it with the truck.

I did some probing of the o2 sensor plug. I have a good ground on pin B, 0.1-0.3 ohms. Key on, not running, I have 11v at pin A and 0v at pin C. Shouldn’t I see 5 volts from the ECU at pin C with the key on?

A friend sent me these pictures, somewhere near Spokane Washington. I’ve never seen a driving one here in Ohio, other than mine.

A few finds so far. the ground path for the IAT sensor has about 2.1 ohms of resistance. I suspect but have not confirmed that a lot of that resistance may be from the C101. I started unplugging, cleaning, and applying dielectric grease to every connector I can find under the hood. In doing so, I found that the ground pin for the ICM looks burnt. Are individual pins available for purchase? I tested the throttle closed switch at the diagnostic port with a volt meter. 0 volts at closed throttle, 5 volts when the throttle is open.

@eaglescout526 I read in your ISA adjustment write up that a faulty throttle closed switch can cause the engine to hunt up and down for proper idle speed. Can you explain to me why that would be? I can see my ISA constantly extending and retracting as the rpm’s alternate from high to low.

Where are the sensor grounds on the 2.5? I know about the ground strap from the engine to the fire wall, but isn’t there single place on the block where all of the sensor grounds attach?

My 2.5 seems to have trouble idling. It will idle at what seems like a normal RPM (no tach) for a while, then the RPMs drop and it sounds like it’s struggling to run. Then, after a little bit, the RPMs rise back to normal. Also smells like it’s running rich. I can see the idle stop moving as the RPMs cycle from high to low. I let it run for a bit with the TPS unplugged, and it behaved exactly the same. I tightened all of the manifold fasteners and there was also no change. The rhythm from high to low RPM seems fairly consistent. What are some things I can check to troubleshoot? I have a video, but it’s too large. What’s the easiest way to share it?
