Porquer

@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?

When I bought my Comanche, the keys came on this neat keychain. I’m wondering if anyone else has seen one of these or knows who made/makes them?

My left window has been significantly harder to open and close than the right window. I took the door card off and tried lubricating the regulator. That didn’t seem to help, so I looked deeper. I found that the slide tube was damaged. With little pry bar action, the window moves more easily. Still a little stiff, but definitely a step in the right direction. I was hoping to find a build sheet in there, but I didn’t. I guess I’m not surprised. It has been reupholstered recently by the PO

Thanks. I’d love to see any pics you can give me of vacuum line routing. I don’t know what’s normal, but it all seems like a mess in there. This thing runs okay, but not as well as I think it should.

I was poking around my engine (‘87 2.5) today and found this connector hanging loose on top of the intake manifold. What is it and where does it need to go? I also noticed that it looks like a couple of vacuum lines are missing from my throttle body. Are there normally four lines that connect to the throttle body? I have two lines and two empty holes. It also looks like a couple of lines have been broken off of this cluster (not sure what else to call it) near the throttle body.

Could you have damaged your booster diaphragm when you slowed down? I’m not very familiar with vac boost, but it seems like that could cause a vac leak that could cause weak brakes and poor running.

Stock should be adequate. I'm on 30s and drive it on the street 90% of the time.

I have an ‘87 Sportruck that came from the factory without power steering. I’d like to add power steering, and I’m wondering what steering gears from which vehicles will be compatible? TIA

Here is a current picture. I’m working through some needed maintenance. I’m keeping it off salty roads and parking it in a hangar on rainy days. The previous owner did a lot of nice work, including new paint and decals.
