Car will not idle...please help!!

[Millah]

Alright...I have a 95 GST that is mostly stock internally except for a big 16g turbo and BOV. Right now everytime i turn my car on, it starts up and immediately loses RPM's and then just shuts off. It actually did stay on just one time since this problem happened, but the RPM's were extremely low, at like 200 RPM and it was very shaky, but as soon as i drove and put it back in neutral it turned off again. The engine aint making any weird noises or anything, and i CAN drive the car so long as i keep my foot on the gas pedal and dont let it idle. Im sorry if this is a stupid question but im not very knowledged with mechanics and such, but could someone please help and let me know what the problem is???? Help would be appreciated, thanks!!!!

This isn't the first time i had idle problems, but its never been this bad. A couple months ago i installed subwoofers in my car i had to disconnect my battery and when i got done and started the car, it would idle very low but it wouldn't actually die. My friend told me i had to let the ECU reprogram or whatever since i disconnected the battery, so the problem fixed itself after i drove for a few days. The problems i have now are the same, except it fully dies now....so could it be a problem with my ECU?? I'm new to this stuff so please somebody help!!

I'd check for boost leaks.
Then I'd check my Idle Speed Controller.

Don't listen to your friend anymore. If he drives a Honda you should have already known better.

I'm also going to assume you have a boost gauge since you have a upgraded exhaust, turbo and BOV. What does the vacuum sit at during "idle"?
And I'm going to assume once more that your BOV is vented to the atmosphere.... please prove me wrong.

Fix your BOV (After you check for boost leaks). Recirculate it to the original location.

I Had the same issue which resulted originally me adjusting the throttle cable adjustment screw behind the throttle body to avoid from stalling out, then when I checked the isc motor 2 it showed it was bad which could be your problem, you just have to check it with a digital multimeter, as listed in the hayes manual. I bough a replacement one of ebay for 80ish bucks.
