No brake or clutch pressure
 

I was installing a FMIC on my car....but quit because the turbo upgrade I had bought wasn't what I was expecting so I put everything back to oem. But now the car iddles at 3000 rpms (i know it's a vacuum leak can't find it yet) but what I'm blown away is why I don't have any brake or clutch pressure?

Some help please

Year and model?

The clutch and brake systems are independent. Just by installing an FMIC they should not have been affected.

The idle is probably a vacuum leak or something stuck on the throttle body but without knowing the year and model we could only guess...

88 turbo II

Follow the "hard steel line" on the Firewall,from the brake booster..it should go to the back of the Lower manifold,and is should hook up there.If that line is not hooked up you get a massive vacuum leak.
The clutch?..I dunno..did you remove the Line or move the slave in order to run pipe for your FMIC?

I didnt mess with it at all. It's so weird.

I found the leak it was some sorte if valve, plastic one that has 3 vacuum lines tuning trhou it...two were disconnected because the plastic had broken of them....I fix it....I'm starting the car tomorrow....or as soon as I get my custom built throttle body plate.
