    So my low coolant light has been coming on (sometimes off), per nov 2011. So I stick more coolant in it, ok fine and dandy for a few days, then just like that "tada" its back on. Before anyone says check for leaks, I've done that already, nothing is leaking, and no coolant in the oil either. I swear I hear a gurggle sometimes, like it has a air bubble in it. I'm just hoping its not doing what I think it maybe doing...

    ok, so on to the other stuff...
    So for around I'd say 6 months or so the car had not up and died for awhile. Well it started to do it again, only this time, more often... I was on my way home from helping a friend, when the car just died, ok fine threw it into (N) and it started right back up, keep going, 2 lights down the road I come to a stop and it just fooking dies AGAIN. This time, it didn't sound like it started back up, but it did (starter squeeled so I knew). Over half way home, it does it again.. ^&*#%$&#!!!11! But starts right back up, right down the road the SOB does it again.... At this point I saw nothing but red, I was so PO'D... So I figured it could be the fuel pump, well that is working so not it, then I decided to test the "maybe its the low coolant", so I dump half a 50/50 in it, and all is well, no more killing over on me.. Now the coolant light is back on, and just today, I was letting it warm up, and while I was in the car heard and felt this very odd vibration, like something was about to crap itself, but nothing did.

    Sorry for the long post, but I can't seem to figure out why it dies on me, or why it keeps wanting more coolant.

    Yeah it could be they tend to leak in different places.

    Check your coolant elbow from the LIM. On my 3800, the seal blew out of 3K miles and had to redo it. My low coolant light kept coming on til I fixed this. When it gets warmed up it lets coolant out and causes there to be low pressure in the system tripping the sensor.

    3.1 don't have coolant elbows.
