I just bought my wife an 03 limited 3.0 . When it is cold you have to give it fuel to start. If you don't it will fire then die. When it does start it revs to about 3k RPM then slowly comes down. When it warm it starts just fine. There are no light on and I just changed the fuel filter. I'm thinking there has to some sort of sensor going out ( fuel pressure sensor) maybe. One other problem I have is when your taking off there is a sort of growling noise from the front and when you stop accelerating it goes away . The car has had previous damage to the front .
