Shes stalling on me..

[Jcovill125]

Don't really know why (that's why I'm coming here for help ) but every time I come to a complete stop and have the heat on, my Expy will idle low and stall..

Curious to know if this has anything to do with PCV stuff or vacuum lines? IAC maybe? or am I way off here?

I'm quiet lost on this one guys. Any help would be greatly appreciated!

Thank you for looking!


Almost forgot. I popped a coil and replaced it a few hours before this happened.. Don't know if that helps anything but figured I should tell.

my 99 XLT stalls when its cold and I put it in drive and stop but clears up after it gets warm. not sure if its the same problem, almost as if its not getting enough gas. im not very familiar with pvc stuff or the vacuum lines so if anyone can clarify these also that be great.
Thanks, Jamison

well, you have the symptoms. now, do the test. you can use carb cleaner, a propane torch (not lit) or water (be careful not to use too much) and go over the lines to see if the idle changes. if it smooths out over an area investigate that hose for cracking/holes.

Here's a write up on the vacuum line stuff if you are wanting to check into it a bit.... always seemed to get worse when it was cold till I fixed it..

it could certainly be a combination of things, but believe you're describing classic IAC &/or PCV line replacement.

Yep, it seems like you may have knocked something loose or perhaps cracked a brittle vacuum line. I use the propane torch method to find those leaks.

I will check the line as soon as it gets back from the shop. had it brought to a shop because me and my dad could not figure out what the problem was with the rear blower.

You guys were spot on. Cracked vacuum line. I must have messed it up when I was replacing the coil. All I have to do now is wait for some warmer weather..
