My money is on that.

yea true but my homeboy told me it could also be a vacume line. and if so which one will it be?

could be both...

could be a vacuum line, as well as a clogged pcv valve. remember, when trouble shooting, always start with the easiest and cheapest solution first. unless you know exactly what the problem is of coarse.

Take off the IACV and clean it first. I always tell people that

Look at the throttle plate for black stuff. If there is some there clean it up. then make sure you have no vacuume leaks any where. Is your car OBD1 or 2?
