What's up dude! I fixed my idle btw.
Anyways, I agree here. I was having a relatively similar issue, for me it ended up being a short in the TPS and a bad Auto Shutdown relay. Cat is also a fairly common issue.

Posts and grounds are all clean and reading 12 volts all around, yes. Guess it's time to start eyeballing some stuff! Wish me luck lol

Aha! Thank you sir, I'll certainly look into it. So basically we've even further narrowed it down to two things, a short in the alternator circuit, and bad wiring going to the oxygen sensors. It's nearly there! I just ran it up and down my road a little and whoa nelly is she running better...
1997, I'll do physical inspections on the harnesses and stuff here in a bit. I'm about to test drive this and see how much better it runs first

Here's the full code list it just threw:
12 battery disconnect
35 cooling fan circuit open or shorted
42 An open or shorted condition detected in the auto shutdown relay circuit. An open condition detected in the ASD relay output circuit. An open or shorted condition detected in the fuel pump...
I just double checked and it threw code 35 just now, meaning open circuit or short in the cooling fan circuit. I'll check that as well. She's gradually running better though

CEL is certainly working because it threw a code for the TPS recently and a while ago for the Cam Position Sensor. That was with an actual OBDII scanner. When I did the jeeps odometer trick, it threw code 12 (bat. disconnect), 42 (ASD relay), and 45 (turbo??) Then it threw out 55. However, the...
I found some bent pins on my downstream oxygen sensor. Thus not allowing me to plug it in all the way. I'll pull a harness out of a junkyard tomorrow. Hope that helps also

Oh I forgot to answer this one. I took the old parts to AutoZone and ohm tested them. When I saw the ohm readings were different, I'd replace it. I did this twice at AutoZone so I figured the sensors were just low quality. So I went to a dealership and got genuine sensors, and they went bad a...
The injectors tested fine all around just now work engine off. I've narrowed it down to the o2 sensors and possibly MAP. Fixing air leaks in my intake definitely helped. And replacing the ASD relay helped A LOT!! But it's still not perfect. We're getting there however! Doing testing as we speak...
I'll give the wires a look. If I find nothing I'll read your thread. Also I'm going to use my brothers noid set to test the OAC just in case. You're a big help man, thank you so much

Okay, for clarity, when I press the gas, the rpm goes up nice and smooth. Normal, very normal. However, even I take my foot off the gas, the idle dips down to about 250 rpm but returns to normal idle after a second or two. However, often it'll remain at a 250 rpm idle. And very rarely it'll...
I totally overlooked the MAP sensor... I'll do physical inspections of fuel pressure regulators and I'll finish looking at the wiring before doing anything else.
It does still struggle to return to idle after being on the gas, especially in first gear and reverse. When I'm on the gas and let...
My bad, by "testing for voltage drop" I meant I put the red lead on the hot post, and the black lead to the ground on the frame and the engine. It stopped working Monday due to volt drop because it was only reading 2v, hot post to ground. Cleaned it off, everything ran great aside from the...
Alright, so I replaced a few couplers on my "custom" air intake, and replaced the throttle body gasket. The jet engine sound is gone and my idle is steady, but it's idling sorta high now. About 1000. However, it still struggles to return to idle after getting on the gas. I think I've narrowed it...
