The whine you hear with the throttle body is easily fixed with a little work with some sand paper on the edges of the butterfly.
ya did all that but the sandpaper on the butterfly was for the stickiness the whine went away when i bored out the iac opening, well the side there the iac mounts up. it was all rough and didnt flow smooth at all.. but then the post the butterfly mounts to turned on its own a little w/o the throttle cable moving.. POS
MY TB is an Edelbrock/BBK unit. I'll have to check it too. Haven't had any drivability issues yet.
mine was too but if you dont have any issues you prob wont. either it will stick and whine or it will be fine. this one that was on my buddys car didnt make andy noise and worked just fine til that butterfly mount broke
