Hopefully fixed the problem by setting the idle a little higher. I think the IACV is ok.

I have an 88 prelude with a low idle problem. from a cold engine start, it starts with 2000 or higher rpms and then after its warms up it goes back down to ABOUT a thousand but then bounces around eve


Hi Lasbs, Check the ignition timing and adjust with a stroboscopic timing light. The correct timing should be 10 degrees BTDC. If the vehicle is fitted with a carburetor, I believe it needs adjusting correctly, or with the Honda carb, it may be easier to replace it. If the vehicle is fuel injection carry out a diagnostic scan. Also make sure that all vacuum tubes are fitted tightly and that there are no cracks or broken joints. Regards John

I have a 1992 Honda prelude that when it starts up it idles at 1100rpms fine but after it runs for like five minutes it drops idle to 900rpms and as soon as I hit the gas it stalls out..... It starts right...


on a cold start car will idle fast till it warms up then will drop to about 1000 rpm, try increacing idle speed so when it warms and drops it should stay idleing

Engine on idle runs high and low, high and low...


Had same problem. Turned out that antifreeze was low causing insufficient water pressure. Could also be a bad sensor. I would check both.

1989 honda prelude enigne idles high then low irratic


I had the same problem on a Rover. There was a leak in inlet manifold that was caussing the problem.
To verify, spray some sealant to temporarily seal the inlet manifold .and the eratic idling should disappear for some time.
If it does, you know there is leak in inlet manifold which you can take of and refit with a new gasket.

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.
