Ok before my IAC valve had a VERY strong suckion to it but today I checked it and it hardly has it suckion at all. So is it bad? I know this is a stupid question but Im curious! Oh yeah car wont idle either.

do you have more than 75k on the car? how often has the PCV valve been changed?
chances are you'll need a new one

the IAC has around 123,000 miles on it but Ive kept up with the PCV valve but i think my IAC has kicked the bucket.

Are you getting a check engine light? If so, what code?

Are your rpms stumbling? especially when cruising to a stop? if so you will need a new IAC for sure. Cleaning it will just make the problem worse, just pick up a new one.

Seafoam wouldn't be a bad idea either.

What issues would a bad PCV valve cause? I'm at 66k miles and still on my stock one

uncontrolled blow-by which gunks-up the intake manifold, IAC, and other related parts.
the PCV valve should be changed at 30k under Normal intervials
