Does this happen when you are in nuetral or when your in stopped in first. That use to happen to me with my 91 accord. I had to get my engine flushed out also my transmission flluid. (At least this is what I was told I had to do.) But it seemed to have fixed the problem. It happened to me when I was in nuetral

may be a timing problem, i dont see why the fluids would cause it to do that. your best bet would be to take it to a mechanic and see what they have to say. one of my neighbors has the same problem with his lude and i havent had a chance to speak with him about that because of a language barrier

i think it's your idle control valve ( a little thing behind your intake manifold w/ 1 wire and 2 coolant tubes running out, about $70 from dealer). same idle problem happened to mine, changed out the icv and problem solved.

It is either your IACV or your coolant could be low. Check the coolant level first and if it is full then it is most likely the IACV (intake air control valve).
