Sorry, the link I posted apparently does not fit the 3.8s. Here is one for the 3.8

They just called me back... As I thought its a fuel pressure regulator that is bad. Its not a cheap fix either. Its $150 part and then they want over 340 plus tax to install it. I have to hold off for now and get quotes at other places. Seems really expensive to me, and not sure how bad it is to install it myself.

Yeah I can't find any 3.8 videos either. For the 3.4 you have to take the throttle body off to loosen up the bottom nut to pull the fuel line. Unless you have really small fingers it's pretty hard to get in there. I'm not sure if this is of any help but here is a small guide for the 3800

I have a very similar problem with mine, and I have no idea what the issue is. I have the 3.8 and it usually start right up cold. I can go drive it and get it warm and then turn it off and it sits then it has a hard time starting. You turn the key and it cranks, but wont start. So after 2 times or so then it will start but its rought starting and the RPM's are all over the place when it starts then it goes back normal. Once it starts it drives fine. I have noticed if you put it in park then it will idle down weird and almost sound like its going to clunk out. Its really hard to explain. Its at the dealer today to get some recalls done and I told them about it. The guy said that it could be fuel pressure regulator. Anyone have these issues before?

New to the forum if it wasn't obvious..
Well it's good you a finding information to solve the problems with the Car.
Most folks join and get the issue solved and then disappear, and that is to bad because there are a lot of neat things we do on this site.
Hopefully you will check them all out.

Thats a long list but most of it is pretty easy.
