inconsistant start up time

[Admiral]

im curious. does the gen3.5 v6 take longer to start then the 4cyl? i recently got the v6. my old i4 started immediatley and my new v6 seems more sluggish. In addition to that, sometimes it starts quick, other times it takes longer. I replaced the spark plugs and i saw that the tips were gone and was starting to burn the porceline. they dont look like they were ever changed. after that it seems to start more consistantly. but consistantly longer then i think it should. occasionally if i make several short stops where i shut the engine, it starts too quick. The car has 105k miles and seeing the person i bought it from, i doubt they changed the timing belt. you guys think thats the problem? i also just put some fuel injector cleaner in a day or two ago. feels a little better, but still not quite as good as i think it should be. any advise please. thanks

sounds normal, if its taking longe rhten say 1 second might not be

clean the IAC maybe

v6 need smore amps over i4 to crank.

injectors dont start till yovue finished cranking so that doenst help too much (they ahve a certain rpm limit or something

clean cold start injector.

Clean all air intake parts, like throttle body, air intake plenum and intake manifold with some carb cleaner, My V6 takes 1 second to start, every time. But that might be because the battery it has is new and stronger than the original battery. And also clean the batteries connecting terminals, that can help it a bit.
