RPMS too low

[dyablo]

As the title mentions Im currently having troubles with my idle. Car was running fine and would idle at 950 rpms via dsmlink. The other day while driving thru town I shifted and was comming to a stop and the car died. I thought nothing of it since my bov is vented so i turbed it back on and the idle was all wrong. Drove to a parking lot to see what might be wrong, nothing but a very low idle that sends the wideband to 16 and I have to keep the gas pedal pushed a bit to have it at 900 rpms. Car runns fine at cruise just cant get it to idle like before. If i try to adjust the rpms via dsmlink they still dont move. I was thinking my ISC might have died, but woudnt that cause rpms to go up and down? I have included a log of my idle at home from dsmlink. What could be wrong?

I'd guess ISC too. If the ISC pintle is all the way in when it died the idle speed would be low. The idle speed only goes up and down when the idle is too high and triggers surging.
Measure the ISC coil resistance and inspect the ECU for signs of burning up the drivers.

For however long you were venting, the ECU has been strangling the system trying to compensate for the error. Give it at least two weeks to get accustomed to being back to what it was built to deal with.
If it was idling okay while venting, then the BISS had also been set far out of range. It, too, will need to be brought back to correct adjustment.

Well I have had the car for just about two years now and I bought it with the BOV venting so I have not moved that although I know its bad for the car. Would setting the BISS again change the idle even when it had good idle before that day? I was doing some searching and found that some connector must be grounded when changing the BISS is this on 2g also? and what connector is this?thanks.

Fix the BOV first.
At idle speed you have high manifold vacuum and the BOV may be open causing a huge leak of unmetered air. That's may be why your AFR is going so lean.
Then measure the ISC coil resistances to make sure they are good, then set the BISS using the options in DSMLink.

then set the BISS using the options in DSMLink.

please explain? im new to the link still.

Theres an option that lets you set your idle through link. Find it, been about a year since I've opened link
