Well I installed a FMIC on my 86 TII swap and I am missing a vacuum line somewhere. I spent the better part of an hour last night connecting random hoses to different locations in order to get the thing running and, it does, but rough.

I have seen vacuum line diagrams but with me I need actual pictures so I can see what I am doing wrong.

Can anyone help me out? Does anyone know where I can find actual engine pics? it is driving me nuts! Right now I have been messing with the vacuum ports on the passenger side of the throttle body and had limited success.

Please help. And if you sent me the pics I will start a photo gallery for future noobs like me

 

Do you have emissions testing in your area? If not just eliminate your emissions control stuff. This will greatly reduce the confusion of the vacuum system as you will be ditching the "rats nest".

 

This is an s4 T2, USDM setup?

 

well I feel dumb. Yea I guess you MIGHT need some info to help me out LoL

The car is a 86 with a 91 TII JSPEC swap. I know this can cause all kinds of nightmares and it is. I am learning roto's from scratch and I bought the car with the swap.

Here is the problem. I installed a FMIC and an intake this week with some time off and now the car is not wanting to idle. I have been playing musical tubes with the hoses to try to make them work but it still isnt working right. There are two small tubes that come off the passenger side of the throttle body, one from some random box on the wheel well, my BOV, and one from the factory plastic intake tube I have been swapping to try to get them to work. Depending on what I have them connected to the car runs better or worse.

I wish I could explain more but I dont really know anything about the car to explain better. I have seen the emissions removed diagram but because I dont know much about the engine it confuses me. I am a very visual learner and if there is anyone out there that can help me out it would be appreciated. My car is on base and I didnt have my camera or I would take a pic and show you what I am working with.

FYI, if the hose gods are kind the car will start and by giving it some gas it will stay started. I had to move it before I left for the day and it was strong when driving just not when braking or letting off the gas. And I dont know what the emissions do-dads look like but I know for sure there is no cat because I wrapped the downpipe today.

Thank you all!
