my wifes car is a 2006 base grandprix 3.8 motor she was driving it today the cruise kicked off and she looked at the gauges she saw the check engine light was flashing temp was normal car lost power and would not accelerate car also will not restart when she was cranking it I noticed a little bit of fluid running down from back to front of the motor under the alternator hoping for just a bad gasket but fearing much worse any help would be appreciated ill try my best to answer any questions if someone needs more information I haven't took anything apart yet just trying to determine if its a fix I want to do before taking it to a garage
need help car just stopped maybe a blown intake or head gasket

Guys...If it didn't overheat..that's not going to cause it to stall.
I'm leaning towards what nik12937 said I've never had a car with a bad gasket not continue to run it'd just overheat I just never thought about the coolant elbows being in the same area I know they are common on these cars I'm going to run codes the weekend when I get the computer on it after I do that ill repost what codes are on it I'm just hoping it is a sensor and not something in the motor thanks ill repost once I find out more information
On the not starting issue, I ran into this on my 00 GT when a coil pack went bad and fried my ICM (the flat metal part that the coils bolt on to). I was just driving along and all of the sudden it started slowing down and would not accelerate no matter how far I pressed the gas. Started missing as well which would explain the flashing check engine light (this means active misfire on 1 or more cylinders). Got it towed home and found a coil cracked so I swapped in a new coil and ICM and it fired right up like nothing even happened. Once you read the codes post what they are. I'd bet they are a misifre for cylinder or 2, as each coil fires 2 cylinders.
The leak could very well be the coolant elbows, but as stated will not cause it to not start up.

I got the codes it showed cylinder 4 misfire and secondary air injection malfunction also I looked at the coolant elbows and there are indeed cracked im gonna replace them and try to determine if it is the coil pack or bad plugs also someone told me it could be a bad head they seem to think it lost compression

the misfire, pull cyl 4 plug check it out. you may just need a tune up. if over a 100,000 miles. or a plug wire may have burnt to a manifold.
coils crack too you can swap them around to see if the mis follows to the new cylinder.
as far as the stalling. has it started again at all? check for fuel and spark are steps one and two. if those are good and its running again all by its self, the crank sensor could be the problem, they never set a code, and they stall sometimes fire right back up, sometimes a week later it will like magic fire up.
the elbows, you seem to have covered. just clean the 4 holes out real well where the elbows go, lube the new o rings with oil and slide them in.
