That's what it was, I had checked several of the fuses but not that one. Thanks for your help boss.

Yea, I figure the back pressure might explain why my air filter would get oil blown back into it 🤣. I read somewhere that oil on the filter was a normal issue with these, but it would actually get a lil wet if I ran it for too long. Drove it for over an hour earlier with a new air filter and not a drop to be seen.

89 comanche 4.0 2wd. So I had issues with my lock cylinder and the ignition switch. I got inside the dash and replaced them, but now the gauge lights and the tail lights don't come on when you pull the switch. I've checked the ground, the connection on the switch, and every connection I could find under the dash without tearing it back apart. Everything seems to be connected and the fuse is good. Am I possibility missing something or do I need a new switch? Seems like I'm probably missing something, but I was all under that dash and couldn't find anything out of sorts.

I changed out the whole vacuum harness and pcv line and the problem persisted. Ended up hearing a rattle in the cats, I pulled of the muffler and there was a peice of my cat that had broke off and was sideways in the outlet to the cats. Busted that out and problem solved 👌 🤣 lmao I never would've guessed that as the issue 😂

I'll have to try to figure that out tomorrow. I guess I got it with them disconnected. I was up under the hood and my dingus of a brother-in-law decided to "help" and started shoving his hands all up on $#!&, then realized they were unhooked and thought he knocked them off. So he reconnected them and it started running like $#!&, it runs better when I disconnect the small line in the middle and the line on the bottom that runs back to the breather. And plugging the holes with my finger is about the same as putting the hoses back on, it starts running like crud again.

I have a 1988 jeep comanche 4.0 6i, 2wd. The truck runs good as long as you have 2 of the vacuum manifold lines unhooked, If not it acts like it choking. Would that be the manifold lines themselves or would it possibly be a sensor or intake issue? I had someone tell me those lines are prone to flaking apart on the inside and clogging up. I'm ordering a new vacuum manifold either way (they're just $40 so screw it.) just wanted to see if there is something else I should be looking into as well.

Awesome thanks guys, it was the ignition switch itself that was sticking after all. Still gotta take care of the nss, but I'll just put a new one on and clean the old one and keep it with my spare parts. Thanks for your time y'all.

Thanks boss, I'll look into that. What would be making the key stick in the run position though? I'm thinking it's either a ignition is worn or the ignition is not unlocking after being put in park. I know some of the newer vehicles have safeties like that but I didn't know if something this old would. Didn't want to throw parts at it so I figured I'd see if someone has ran into it before.

I have a 88 jeep comanche 4.0, 2wd, automatic. When I'm put in park after driving the key doesn't want to turn off, and when starting it, it has to be in neutral or it won't start most days.
