Anybody have a vacuum routing guide for the 86-87s?

[OneLethal87GN]

I saw the guide for the older hot-air cars, but none for the 86-87s. I think my problem may be vacuum related and wanted to check all hoses before looking elsewhere. My car seems to want to cut off every time I sit at an idle. My IAC counts go to 00. I replaced my IAC motor with a new one and no change. My O2 counts go down to between 007 and 000 when this occurs. My only remedy so far has been to put one foot on the gas and one on the brake to keep the idle over 1,100 rpms to keep the O2 counts normal and keep the car from cutting off. This is getting very annoying and also kind of embarrassing to have such a high idle while sitting at a light, especially with only a 3" downpipe as my exhaust. Any suggestions on either my problem or somewhere to get a vacuum hose routing guide from? Thanks.

I had a problem with the IAC like that once. Turned out to be a valve spring problem. I might be wrong,but,if you don't set a code it's probably something not set to code like mechanical thing.

Yep, there is a vacuum routing page found on gnttype.org website.
