CIVIC TROUBLES??? ('94)?
My '94 civic has been acting wierd lately. Whenever I stop at a red light or something, the engine will rev up to about 2k rpms then go back down to idle and continously do this as I am sitting at the red light. What could be causing this and how to right the problem. Thanks!!

have u recently installed a cold air intake? and it sounds like ur o2 sensor. i dnt think that 94 have sensors for the air intake. but if u did hook up a intake and not hook up the pcv vaulve that would do it.
