my car dies when i brake

[Kslice88]

ok, first when i start my car it idels at around 2500 rpms for about 2 sec. then it drops to 1000rpms and revs up to 1500rpms and then drops and it keeps doin it, i think that it does that because of a bad o2 senser. now recently when the engine heats up ill be driveing at a steady spead and it will jerk a little and then i push in the clutch and brake and the rpms drop really low and it will die if i dont rev the engine. please help im getting frustrated

Might want to check out your isc motor. The brake booster works off of vacuum and it might be putting too much of a draw on it or something or have a leak in the line that goes to the booster. If your idle is too low from your isc then pushing your brake could cause it to die. I am basing this off of experience with a 2g turbo so i could be totally off though...
