ka problem

alright guys...heres my dilemma...while driving my car, after it warms up, when i put it in neutral the rpms drop all the way down and some times it actually stalls out...ive been told that its probably a vacuum leak...what do u guys think...and what would be the best way for me to fix it...any info/advice would help thanks

you might want to check your AIV...other than that im not sure. It could very well be a vacuum leak, im not really sure.
