Hello Honda gurus in the house, i need your urgent help. I have a honda accord 1996 (a.k.a Honda Bulldog). I'm having issues with the car. First is that the idle run is very high, 1500 - 2000RPM. I took it to the mechanic, they services the throttle body and IACV and FITV but the problem continued. Another mechanic now used foam to block the two port holes inside the throttle body and the problem of high idle run stopped. It runs now at about 800-1000RPM. Another issue started, the car just stalls intermittently mostly when you want to move the car, like if you start it starts normally, idles normally, but once you engage the gear to drive and press the throttle pedal, the car will stall with the dashboard lights on. If you start it right after it starts normally. This happens randomly that i cannot predict when it will happen. If somehow i manage to make it not to stall when it want to by quickly depressing the gas pedal hard it will move but at any point, i brake that the car will come to a stop, if i want to move again as in press the gas pedal the engine will go off. As a result at times the car goes off on the road.

I have gone to several mechanics and car electricians yet the issue has persisted. Sometimes if i go to the mechanic the problem will not occur and i will not be able to simulate it.

In the process of trying to resolve the problem, i have replaced the following: fuel pump, distributor, fuel pump relay, plugs, throttle body.

I will appreciate any help to resolve this problem.

Replace entire intake, with a clean toks with all its components intact

Demrich:
sir what do you mean by 'entire intake' cos mine is always bt 1500rpm to 2000rpm when i start in the morning bt wl go bt 700-1000rpm when i engage the gear. The problem started when mech spray throttle body wt injector. cleaner.

Mementoes:
This seems like a vacuum leak problem. Does this stalling get worse when the engine is hot?

Mementoes:
If there's no vacuum leak, then you should replace the IACV. Yes, it can cause intermittent stalling. Anytime your foot is not on the gas pedal, the IACV is in operation.
Hope your engine timing has never been messed with?

Thanks. I will replace the IACV and report back. I don't know if I have issues with timing. D car drives well oda than the issues I mentioned. Infact I travelled more than 400km with the car.

I also noticed something though wouldn't know if it has implication, as I was driving at night, d dashboard lights flickers intermittently especially that background light on d dashboard n d headlamp seem to b brighter as d engine rev up.

Thanks so much @Mementoes
