Hey guys,My car has done this twice in the last two days. It only happens after my car has been sitting outside in the cold (at work). When it's in our heated parking it is fine. I'll go to start it, it'll start and the RPMs will go up then drop down, flutter, then stall. I'll start it again and it'll start but I let it warm up for a while and then it's fine. The gas smell is more profound during this as well like it's running too rich. What do you think? Maybe a bad batch of gas? Throttle-positioning sensor? I'm thinking something involving fuel delivery. Battery is about 2-3 years old. Thanks.

Oh ya, and it only does it after being outside in the cold for an extended period of time, 4+ hours in sub 30 degree weather. It's never done this during previous winters (before the supercharger).

Mine sometimes does that now since the s/c install,mostly first start-up in the mornings.I think it's normal,because the ecu floods the engine with fuel.

Same prob here, but mine does it all the time, no matter the weather or where it's parked. If it is cold (i.e. hasn't been run very recently) I have to hold the gas until it is warmed up or it will continue to die. Must be a S/C prob???

It only does it for me when it dips below freezing.I learned a trick that has worked for me.Turn the key,wait 4 seconds,then crank the engine.It's stopped doing it for me since I tried that.I know I'm weird.

Phew. I'm glad I'm not the only one, but not pleased with the issue. I have remote start and hope it starts when I hold the button down! I'm guessing it's an ecu thing, probably pushing the same amount of fuel regardless of temperature and flooding it at first.
