sometimes they are bad and cleaning them wont help. but if its trying to die and idle surges you might want to look for vacuum leaks

Your fuel filter may be clogged, sounds like the problem I had on my old civic.

I'm assuming you took your iac completely out of the car, thus opening up your coolant system right?

You have to bleed the coolant

Inliner

is it just idling low? what vehicle? have you tried to adjust the timing with a timing gun?

if your 0BD1 check the FICV under the throttle body some times you need to take off the back and tighten up the big white disc with a large flat tip screwdriver.
