Kalal92 Posted August 11, 2019 Posted August 11, 2019 Low idle or goes up-and-down fine while driving but after coming to a stop or neutral will drop again or die. Sent from my iPhone using Tapatalk
eaglescout526 Posted August 11, 2019 Posted August 11, 2019 Well the vacuum lines on top of the valve cover looks wrong. 86's are a different animal but one is supposed to go to the air box and the other goes to the throttle body. Everyone will tell you to check your manifold bolts as well.
Cheapamanche Posted August 12, 2019 Posted August 12, 2019 Check your manifold bolts. Sorry I had to say it 😉
Kalal92 Posted August 16, 2019 Author Posted August 16, 2019 I was looking online and seen some 2.5s with two hoses for the PCV (in and out) I didn’t know this because when I first got her it had a crossmember to each pcv ports going straight to the throttlebody it was like that and so I didn’t question it. If this is right is the front end and the back out or vice versa the only thing I could find is the 4.0 unless it’s the same?Sent from my iPhone using Tapatalk
Kalal92 Posted August 16, 2019 Author Posted August 16, 2019 Sorry didn’t mean to split that Sent from my iPhone using Tapatalk
eaglescout526 Posted August 16, 2019 Posted August 16, 2019 I believe that front valve needs to go to the air box. It looks like there is a opening at the bottom of the box that is plugged. Like I said ‘86 is a whole other animal for the Renix years.
BeaterComanche86 Posted August 16, 2019 Posted August 16, 2019 Here’s the set up on my 86 with 2.5. Front of the valve cover seems to go to the throttle body and the rear to the air box.

BeaterComanche86 Posted August 16, 2019 Posted August 16, 2019 @Kalal92 Did some digging and it seems to be called a ventilation valve. Here’s the picture I found.
cruiser54 Posted August 17, 2019 Posted August 17, 2019 check the intake and exhaust manifold fasteners to be sure they're snug. And check these hoses.
Kalal92 Posted August 23, 2019 Author Posted August 23, 2019 Took the Comanche out for a quick drive after changing the hoses, if you can see and hear in the video after going into neutral and turning almost dies hitting pedal and doesn’t want to go. She starts up every time with no problem just doesn’t want to stay running without a high rpm Sent from my iPhone using Tapatalk
Cheapamanche Posted August 24, 2019 Posted August 24, 2019 Have you tried blowing smoke into the engine to see if it leaks out anywhere? Does this seem like a sensor issue, maybe MAP sensor? I don't see a vacuum line hooked up to the map. Should the 86 have one?
Cheapamanche Posted August 24, 2019 Posted August 24, 2019 Nevermind I see it. Try the smoke trick. Take a cigar or cigarette and blow it into manifold vacuum and see where it goes.
cruiser54 Posted August 26, 2019 Posted August 26, 2019 Simple to check for vacuum leaks. don't need no smoke... At idle, spray carb cleaner on suspected areas. Idle will change immediately when you hit a vacuum leak.
