Question type: Maintenance & Repair
I have a 2011 Chevy Malibu, mileage is 39000. it's
the winter season and my car wouldn't start. I turn
the key to the on position, and I hear the fuel pump
humming. It'll turn on but it won't start unless I gas
it while trying to crank it over. When idling or
stopped at a light, there's a VERY light shaking. I
know newer model cars don't really need a tune up,
but what are the odds i need a tune up? If not that,
what else might it be?

mileage wise plugs should be good,never hurts to replace them. Also could be IAC valve,throttle position sensor,vacuum leak.Is the check engine light on? if so have code read,fuel pressure issue.
Have it scanned for trouble codes at a local parts store and post the codes here or some some Google searching on them. Your spark plugs should be still good.
Have it scanned but like cj said it sounds a vacuum leak. Could it be too early to need a MAF sensor?
