Hi.  
My Civic was bucking while driving after warming up. When letting off the gas it would almost appear to stall and then when adding gas again there seemed to be a delay before it would react. I replaced the Idle air control valve and the bucking has disappeared but now it is hunting for an idle when I’m stopped at a light. It runs fine so long as its in motion. Thoughts? Thank you!

Have you tried cleaning the throttle body?

Hi. Thank you for the quick response. I do spray the throttle body when I had it off to install the IACV.

To clean the throttle body you must thoroughly clean both sides of the throttle plate. I am always impressed by how much gunk is on the back side of the throttle plate.

I had an 82 Toyota Starlet many years ago that had a fuel filter that got pretty clogged up, it behaved very much like you are describing. Replacing the fuel filter fixed the problem.
