Anti-lock brake light and CEL-HELP!

[TalonTSIYHL]

HELP!!! ASAP
Whenever i press the brake, the antilock light and a CEL comes up untill i let the brake go. There is also a click sound from the ECU. It doesnt matter wat gear im in or if im in park. The vac also decreases by 4 and the RPMs go down. Sometimes they will go so low as to the car wanting to staul. I would assume that there is a vac line that is not connected but i dont see any. Is there a specific line i should check? Or what else could be causing this?
Thanks in advance.

I would guess something with the brake booster. Check for vacuum leaks. I wonder if the brake booster goes bad?

hey thanks for the imput, but i found that the green wire connected to the lower left part of the thermostat was frailed to one thread left. I rewired it and no more CEL, tick, or antilock light.
