1990 Honda Prelude 2.0 si F.I. Idle Fluctuation


This problem is a little bit hard to coz you need to check the following throttle body, fast idle valve & the IACV valve. First the throttle body it must fully closed during idle and the TP sensor voltage must be 0.5 volt. The fast idle valve is wax type there is a 2 small hose pass below of this valve, if the coolant water is not circulating the valve will not closed. You can check it by touching the lower portion of this valve after 1 min. Regarding the IACV you can check if this is the fault by removing the hose connecting the throttle body and air filter. there is 2 small hole near the opening of the throttle body, while the engine is running at idle close one by one and see which one cause this problem.I hope this will give help to your problem.
