2000 2.5 Se....I start it up and it starts fine, but have to keep idling it for a while or it dies when cold. ( auto tran). guy I got it from said he ran sea foam evry once in a while to make sure the fuel injectors stayed clean, but I wondring if they may need to be replaced ? Or is it something else. I am asking as its freezing cold and I have no place at my own place to work on it, so want to get a good idea what to look for before I do anything so as to not be wasting time. thanks for any help.
