Help! My idle is too low & sometimes dies

[Deathmug]

For some reason my car is idling at about 400-550 rpm. It also dies sometimes.
I was wondering what I should look for in my logger to find the problem.

Also, I’m about to do a turbo swap. My stock turbo is so messed up it’s leaking a little bit of oil into my exhaust. It causes it to smoke a good amount. Not sure if that’s got something to do with my problem.

Here’s a log I did the other day.

Sounds like your bov is vented. If this is the case, recirculate it. If its not the case then you might have a bad isc on your hands.

Are all of your vaccuum lines plugged in or capped off? You could try adjusting your idle screw, or pick up another ISC as posted before.

Do you have any other drivability problems?

just to add to the list, adjust your TPS too

Dont really have any other problems. It's a brand new motor & a new ECU also.
I just got my logger & that log I posted is my first. I'm not sure, but it looks to me like the maf isnt reading accurately.

Is the idle screw on the ISC itself?

 

[out there]

i had a problem similar to this in my car for a while, if i remember correctly, the battery was sub-par

The screw is on the top of the throttle body, in front of your vaccuum lines. There might be a black plug covering it, once that is removed the idle can be adjusted with a phillips head screwdriver.

Here it is circled in purple.

I even made it easier for you

*oh, and if someone notices the vac lines being hooked up wrong, I know.. I've since fixed it the right way

I had a similar idle problem after my battery had been disconnected. The factory manual said to start the car and let it idle for about 10min (don't touch the throttle). I thought it was going to die a few times but it cleared up and started to idle like normal. If you had your battery disconnected you might give this a try.

Just to update everyone.
I got her up to a good constant 900rmp idle.

I tested the battery & it was a little low, so I fully charged it.
Also, I pulled the ICM & tested that too.
You have to use a multimeter to check between pins 1-2, 2-3, 4-5, & 5-6. They should all read 28-33 ohms. My ICM checked out, so I just cleaned up the pins and put it back in.

I also did what Seth said. That seamed to help as well.

Thanks for the input fellas!
