umm ... question?
do you have anything blocking off the breather line on the intake? it doesn't look like it in the video.. that will really **** the idle up .. trust me i did it to see if it was sucking or blowwing air out..
it drove fine..
as far as the lean fuel trim code YES it's related to the idle.. that IS a maf issue.. or intake issue .. i had that issue before .. and we thought it was an injector pulsewidth issue.. and while that can be part of it after we fixed the injectors i still had an issue... also vince needz to make sure the maf is scaled correctly that could be it as well but he should be able to tell that as he did with my car

The thing that leads me to believe it's not an intake leak is, why when i started it with the stock injectors and tune, it idled perfect, then the only thing i changed was the injectors and tune, then up pops the idling issue. I will say this, if i have a leak, i WILL find it tomorrow. Thanks for your help. My IM is not work i guess?

My vacuum is about 20 when it's at idle, if that gives you any kind of indication.
I realize it might be a little different since I have the vulcan manifold, but not 100% sure. 17-20 is probably around normal.

those injectors r fine on stock rail, atleasy mine...I'm a 06 with cylinder shape rail( yes some cobalts have difrent shape rails, I've seen some with flat squarish ones...hmmm...
Unplug ur first 02 sensor...turn the car on...does it still do it? (let it idle for a minute or two)

So, i haven't been on in a while and thought i'd give an update for anyone interested. I fabricated the air intake. I've been having a fit with my idling issues, Vince from trifecta has been workin overtime with me on this.
Other than the idle issue the car runs GOOD. But my oil seals on the turbo are going out already, it's starting to burn oil, which SUCKS!!! I'm not sure if i should have ran an oil pressure restrictor or not, but i haven't even put 100 miles on it and after this weekend i'm gonna have to take the turbo back off and rebuild it... Hope i make it to carlisle, and not roll in puffing smoke out the pipe, lol.... Sucks cause i was thinking of hitting the dyno while i was there but, i don't want to push it now..
You guys saw the idle issue on the video, well the car was also showing lean fuel trims at idle. I've never been able to find a vacuum leak which is what it acts like it has. So we reflashed the ecu and put the stock injectors in just to see what happened to the trims at idle, and they instantly went rich. So it seems the problem is with the injectors. We are trying a new tune in the morning, back to the 42's and i willl see what happens. Wish me luck...
Sorry for not posting more videos, it's been raining buckets here so i have not really drove the car much

Thanks dude. Ya, I should have one up in a week or so. I just dont want to make one until I have the dyno numbers. My friends dad owns one of the only dynos left in town so it shouldn't be much of a problem. Just need money

The turbonetics website/forums say they do not recommend oil restrictors on any of their turbos, so i'm just lucky i guess, stupid seals,lol...

Well, i thought it had one, but i think that's just a screen type filter. I got it from a guy who ran it on his srt and it came with the exact fittings he had on it, minus the oil feed line, so i just figured i'd be ok. I don't know if the srt has less oil pressure or if the spot they feed the turbo from has less oil pressure or something. Too late now i guess. Hope i make it thru the weekend, i'm traveling about 120 miles each way, prolly gonna smoke like a freight train by the end of the weekend, lol... Wish i knew where i could get a restrictor fast.

I had the same problem, but I just got a flange that has a pinhole inlet and put it on and no more smoke. Of course, if it's blown the seals, then it's done for. I wish you luck. I'm still in the process of fixing my car as well, running rich as ****, but we think it's because I have an exhaust leak.
