hey i have a 92 honda prelude Si. The problem that i have now is that when i start the car when its cold. It ideals at 1500-2000. And at running temprature its ideals at 750-800. Is it normal to ideal at that range when its cold. Anways i have already cleaned the IACV. So now do u guys think that i need to clean my FIV. Any suggestion are welcome. Thanx.
