I copied the plans for cootees isr pipe mod, but when i went to start the truck, it idles for a second or two and then slowly stalls out. any ideas why this is happening? i made sure everything was connected, but still cant solve the problem.

its a 3.0 auto by the way.

Do you have both small hoses attached to it? Show us a picture of it. Someone might see what is wrong.

traben27

yeah i'll try to get pics asap...i hooked both hoses up, but the hose closest to the engine is farther to the right than most people put it...could that have an effect on it?

ChickenLover

Yeah, get some pics up.

traben27

i'm probably missing something obvious...or just totally did something wrong, but heres a pic...

ChickenLover

It looks good to me. You must have a bad seal on the pipe somewhere. Either your clamps aren't tight enough, or your two connected hoses aren't holding a proper seal.

Paul H.

Mine is hooked up just like yours. I don't see anything obvious. By the way, what is your warm idle?

traben27

actually...its usually pretty low for the other cars i've driven...around 800 rpms.

Paul H.

Thats what it should be. You can put the original stuff back in a see if it still stalls that way you will know if it is the mod or not.

traben27

well crap i cant do it now cause its dark, so i guess i'll have to do that tomorrow. oh and by the way, i can keep it running if i hold the pedal down, other than that it drops down and shuts off.

did you touch your airbox at all, or maybe mess with the afm? My buddy messed up the connectors in his afm and it would fire and die.

traben27

well yeah i touched my airbox...it was all connected to it haha. but how did he notice it was wrong and how did he fix it?

traben27

so i checked all my connections again, and the hose barb closest to the afm seems to be probably too loose, but im not sure on how i could seal it better. anybody have any ideas?

rentedmule

Do you mean the hose barb connecting one of the vacuum lines to the air tube? I had trouble sealing mine so I put some urethane weather stripping adhesive around the outside of the barb where it went into the tube. I'm sure silicone or something would work just as well as long as you don't get it into the intake tube. Even when mine was obviously not sealed properly it never stalled though. Good luck

Godzilla

well he decided to open up the afm by those 2 tempting screws on the side....bad idea..just makin sure you didnt while doing the mod for whatever reason

traben27

yeah that barb. i'll try silicone because i'm pretty sure thats my problem, everything is fits tight or is tightened down...

godzilla-nope i didnt even think of doing that...i'm wondering why he even thought of that.

When I saw your pic, for a second I thought that was my pipe cept i have the adapter on the end to the Vafm and a cone filter.
But I know what you are talkin about, or might. When I did mine the first time, I didn't use a replacement pipe, but the tubing that was originally there for the intake system. Mine would start, but then would slowly but surely die. The reason for mine was that there was an air leak behind the vafm. One of my connections wasn't completely sealin and the added flow of air behind the vafm was causing it to die. Check all your soft and hard connections.
To seal your connections between your hose barb and your pipe, try using JBWeld. Thats what I used, and its worked great for me.
Hope you get things worked out.

x2 for jb weld. I have actually drilled and tapped it in the past.

did you pull the efi fuse..it may just be the computer chokeing the motor sort of speak

traben27
