Air going out?

[GAINMOB]

ok...so upon start up...i can barely feel the suspension filling up...i've always heard it...lately...it airs up when i start it...but after i drive and stop at a light...it'll air up more...is this a precursor to what everyone has encountered when their air suspension crap'd out on them?

so basically...it sounds/seems as if its not airing up all the way until i come to a stop after driving off...

any info? input? especially those who had theirs go out...
