err, engine can start without hicccups, rite? engine sucks air
when its running, rite? got air sucking sound also logical, rite?
no worries as far as the signs tell. IMO, if ur engine not sucking
air, then u got a real problem 
the other thing u may wanna check is for leaks in ur vacuum pipes,
air box and funnel. any breakages in these places will usually
result in a louder induction note. can check on ur own if u have
some idea of ur engine layout. but if u are a complete idiot to ur
own car, then probably gotta pay someone to do it for
u...........
