what happend. I was running the car and just got boost fixed i was about 10.4 lbs of boost and it started running like crap. Now it wont idle. Hope i didnt screw nothing up.

 

When it does idle is real bad it has about .14 lbs of vac on the profec b not for shure on boost gage. no smoke.

 

You might have a bad vaccuum leak try checking all the vacuum hoses etc.

 

You need to give alot more information. IE what you were doing exactly, what you fixed before, how many miles, what your mods are, etc etc etc etc

 

well i was goin at wot. i have downpipe intake and boost controler. the motor should have somewere around 20k

 

Could it just be the plugs? I start it and it dosent want to idle. But if i give it a litte gas and keep it around 1k then it seems to be fine. The Vac is the same as it was at 1k rpms. It just dosent want to idle. When i go down the high way it runs and boost is good but it fills like it is cutting out. What does everyone thank could it be blown?

 

Yep, it could be blown.

 

Check your MAP sensor hose. It's on the firewall kinda behind and a little above the compression tube (elbow connected to the TB).

 

Sorry dude bad news.

 

Ok guys i dont thank it is blown when running and going down the street under boost it seems to be fine just a slite cut out every now and then. when I stop it goes down to about 200rpm then back to about 800. But when i touch the brake it will go back down to 200 if i let off then it goes up. When on the brake the vac goes up and down. When i let of it stays constant but not as high as usual. If i touch the gas at all to try and bring the rpm up it falls on its face but then comes back up. Not for shure but i dont belive its gone. Maybe it is. But i am hopping its just a vac line off somewere. Whats everyones oppinion? What is the chance it is fine or blown? 50/50?

 

My guess is that you cracked an apex seal, but that all the parts are still in the groove. That will make it idle rough, but it will still feel pretty good on boost, and the idle smoothes out at 1000+ RPM (light pressure on the gas). I would recommend staying off boost (so you don't lose the seal and ruin your turbos and housing $$$) and getting a compression test. If it is blown and you can get it rebuilt before it really grenades, it will cost less than if you keep driving and really blow it up.

That said, I don't seem to follow my own advice. I kept driving my car after cracking a seal and really killed it soon after.

what would it cost to get the seal replaced? How hard is it to do?
