Better get this one to a mechanic. Sounds like you blew a head gasket.

CEL blinking smoke coming from exhaust, rough idle

White smoke is indicative of burning coolant. Gray smoke is burning oil.

Have a compression test done which will often give an indication of evolving head gasket problems. If the coolant level is going down, and there's no obvious leak, its a head gasket.

Coolant light on and leaking coolant... now white smoke and car will not start

You really won't know until you take the intake off.
There could be other problems that caused the leak before the intake cracked.
Until the intake is replaced you won't be able to do a pressure test of the cooling system.
Make sure the thermostat is replaced since it could have been damaged from the overheating episode.

2004 pontaic grand prix white smoke coming fro m exhast

Quit driving it. You have blown a intake manifold gasket or a head gasket. 3.4 engines are known for blowing intake gaskets. Check your oil, make sure it is not exessive or milky in color. White smoke is caused from water/coolant entering the cylinder.

98 grand prix 3.8 non-supercharge starts but wont stay running have to keep foot on gas pedal to stay running blows out white some trough the exhaust. no coolant in oil what is causing this

If it is blowing thick white smoke that is coolant. You can lose a head gasket in places where only coolant passages go through so you don't always get oil/coolant mixing when this happens. Take the radiator cap off and see if air bubbles through it. You can also try pulling the spark plugs to see if one or more looks really clean.

Sorry to inform you of the bad news but the white smoke is engine coolant burning off and the rough running condition is also associated with coolant leaking into the combustion chambers.This will be a head gasket repair, basically a head job where you will need to machine the heads down and install new gaskets from the heads up.Get back to me if you have any more questions, thanks and I hope I could help!!!
