just bought a 2004 used g35 coupe w/ autostart yesterday...

however, when i click the remote 3 times to start it... it starts up nicely but then idles low and then dies... it is decently cold out but i'm not sure that this should be an issue in the cold weather...

there have also been 2 or 3 times so far where I've started the car regularly with the key and it did the same thing.

can anyone offer any suggestions as to what might be the cause of this/how I should go about correcting it?

I should be covered by the dealer under the NYS Lemon Law for 60 days...

any suggestions/advice/knowledge would be much appreciated...
