    I have the 2004 3.8 non-SC, lately when starting warm, the car truns over but dies right away, I have to press on the throtle a little to get it to keep running, I am thinkiing MAP needs to be cleaned?

    I've seen them at over 300K and I've seen them fail early on. Go with it, until it says to replace it.
