2002 Dodge Intrepid 2002 Intrepid starts hard (10-15 second

2002 intrepid starts hard (10-15 seconds) when "cold" (summer or winter but worse in summer). Once its started and you go to a store and come out its fine. If you go out for lunch at work after its sat for 4 hours it is hard starting again as well as the end of the day.

I've checked the fuel pressure a couple times and its well within the Haynes book spec's. Very little pressure bleed off as well even after a few hours.

Can't think of what it could be. No codes with key but do get an occasional high side O2 sensor code but it is very intermittent.

Thanks for the help.
