occasionally when i'm sitting at a light...stopped and the car is on...it feels like the engine hiccups...it seems like it revs up (although the tach stays the same) and i can feel it shaky with my feet...anyone have an idea of what the problem could be...thanks

 

Mine does that too, i think it when the ac turns on.

 

does it race up and down when its not in a gear? if so its the iac, idle air control valve. mine went out like 2 mos ago. not hard to replace.

 

it's prob. something like that...i'm thinkin of taking it to acura to get it checked out...i just reached 85000
