alright, So I went to fix my exhaust leak, I took the manifold off with the turbo, I replaced the exhaust manifold gasket and the manifold to turbo gasket, well I reinstalled it, and made sure I installed EVERYTHING like I took it off, made sure all connections were back like the o2 and maf, then went to start it, and it always idles a lil high when I start it up cold, but this time, It idled at 2 grand, ok so now im worried , but I remember when My friend messed w his exhaust it did the same thing, It had to relearn, and when he undid the battery cable and put it back on, it worked, so I tried this, and it brought the idle down to 1500, still a lil high, but i usually idle at a cold start around 1300 so im like ok ill give it a lil time, then it started acting real strange, going from 1500 to 1300 to 1500 sparatically, and tons of blue smoke is coming out, this is not from the gaskets being burnt right, I mean its not smoking blue untill like 30 seconds and then tyhats when the idle goes sparatic, turbo was spinning soo soo freely and had no shaft play when I checked it. I dont knwo what to do. PLEASE help me.

First off, adjust your IACV that probably ur idle issue.

Sounds like mabye you did somethin to ur turbo that blew it. I sure hope not.
Is the turbo really loud when you drive it? Cause if so

mjjstang · 11-03-2004, 03:39 PM

IDle always settled back down to 850 after like 3 minutes 2 days ago before I took the turbo/manifold off.

mjjstang · 11-03-2004, 03:56 PM

ok went out again and noticed this time when I started it, It acutally seemed like a normal idle, then when I gave it a lil gas it started doing the crazy shit again, this led me to believe that mabye my throttle cable was messed, but I checked , and it seems to be fine, the idle just keeps goin up. it was at 1700 this time. it couldnt be the iacv, I didnt touch it, do I need to go drive it around for the computer to relearn something, I dont know, this is so weird.

nismostate · 11-03-2004, 09:29 PM

yes, try driving it until it's warm. is it doing anything weird when your driving it? is it smoking constantly? having a high idle is not that big of a deal. what does "crazy shit" mean? you gotta be more specific. if driving condition is fine, adjust the iacv. doesn't matter if you never touched it. it could of been off, all along.

mjjstang · 11-04-2004, 01:03 AM

no it is not fine, the idle goes to 1700 then cuts to 1300, then goes t o1700 to 1300, like ecu is controlling something, the prob, is that it was fine before I took the turbo off, I know I put everything back on though. also would a bad o2 sensor do something, I may have knocked it when I had the exhaust off. before this, idle would always settle to a nice 850, exhaust was great, now in my garage, after 30 seconds you cant breath, it just fills with a cloud of blue or white exhaust, donno what it was, it was kinda dark. some people have told me it could be a vaccum leak, but I checked and rechecked, also the hot pipe was the only thing i took off as far as charged air, and I made sure that it was very very tight, so no leaks. donno.

mjjstang · 11-04-2004, 12:01 PM

bump, please someones gotta know what is going on, I mean why would a prob like aicv only happen after I reinstalled turbo, what could I have done wrong. someone please help me.

kingsol · 11-04-2004, 12:49 PM

well, why don't you try adjusting the icv first...

mjjstang · 11-04-2004, 01:13 PM

ok more I was really worried about how the blue smoke was coming out, it was just too weird how it only happened as the rpm got messed but the aiv would have nothing to do with blue smoke, anyhow, I actually drove it, and it drives fine just like normal, BUT, now Im noticing that there is just whitish smoke coming from the intake manifold area, and bubbling squishy sounds , I will get at it with a light and take a look, the aiv doesnt have anything to do with coolant right, I remember a big line going to it , but it is prolly just air, anyhow, I will go adjust the aaicv because my rpm will still slowly rise when in the garage at idle, im noticing a lot more sounds now that I have an exhaust so It should be easier to diagnose things. thanks for the iacv idea, I know I should have adjusted it when the first person told me to. i just cant see how it got messed up right after reinstalling the turbo. ill let u know.
