I have heard great things about seafoam and have used it on my civic a few times. I just add it to a full tank. I am currently having a little rough idle issue, and i'm curious if I should use it to clean out my throttle body? I've heard spraying seafoam into your throttlebody while the engine is running can have great benefits, or cause lots of damage. Thanks!

seafoam isnt a one fix all deal. if you have a rough idle feed half of it through your vacuum line and half of it in your gas tank. that may or may no help your rough idle.
