1996 lhs hard start

My father has a 1996 lhs with 50,000 miles on it. In the last two years it has had new lower and upper intake gaskets, fuel pressure regulator and iac. It use to miss at idle and idle to slow before those repairs wer done at a chrysler dealer. Over the last few weeks it has got to where it starts hard or have to give it a litttle gas with foot to get to fire up. Has anyone ran into this problem out of the 3.5 v-6 before i get to deep into it. Other than that runs fine after started. Thanks
