Well I ended up getting a (gunked up) junk yard throttle body and IACV back around January. I cleaned it well and took one of the recommendations of using LPS lubricant on it. The car ran well after that and my code stayed off...until last night. I never even thought my IACV was the culprit to my newly developed lumpy idle and slight hesitation at throttle tip in. I pulled it off last night and it was practically frozen up. After filling it with carb/choke cleaner and swabbing at it a couple times it started spinning freely again. I am little disappointed at the fact that it was frozen up after only 6 months or so. I don't want to spend the money on a new one but cleaning this every 6 months isn't really something I want to have to do.

Has anyone ordered one of the rebuilt throttle bodies to see if they come with w/ a nice clean/new IACV on them?
