Idle problem, falls to near 0 coming to a stop then starts pulsing?!

Hi, I am a newbie here. 7 owner for 2 months .

Anyways, I have a problem when ever I am driving and that whenever I come to a stop, my RPM falls down way below idle and very close to 0, but the engine doesn't stall. It starts pulsing from from as high as 300 and then very close to 0 constantly.

I have to hold the brake and slightly hold the throttle to keep it at idle while at a stop, afraid of it stalling(which it has one time).

Any idea???


Thank you my bro's

Almost certainly a vacuum leak.

I would also wonder if someone played with the timing or the idle mixture.
