When starting my car in the morning, it will idle up for like 10-20 seconds then die like its got a vaccum leak, but i have replaced all the vac. lines. anyone have any suggestions???

You might want to check the IAC (Idle Air Control) motor. You can probably find some more info on how to check/test it on some of the other Turbo Buick sites. I'm not sure what the cost is since I replaced mine a long time ago but do be careful if you decide to replace it because it is somewhat fragile. The first one I had broke during installation by a GM Master Tech.

I repaired one of my problems i had an injector o-ring leaking really bad on the manifold.........car starts a little better now still dies a coulple of times.........hopefully this weekend i can hook my scan tool up to it and see what the deal is.........hoping all i have is a bad sensor or something.....

when i try to start the car in the morning or when its been sitting for a while, it will rev up then die. I have replaced every vaccum line, iac, tps, o2 sensor, injector o-rings, and every upper gasket known to man... Im at a loss now. i hook up a scan tool and it shows that the car is running really lean. Anyone else ever had this problem? Any help will be greatly appreciated.
