H22A4 Ideling

[Squalled]

Hey guys,

Is it just me or does the rpm drop down low and come back up again? I have a friend with a Prelude VTIR as well and his does it but doesn't drop as much as mine.

At times it's gone to 0 and then back up. It's even turned off a few times while driving and the green key light comes on if it turns off. Any help is appreciated.

sounds like main relay

mine was doing the switching off and green light flashing crap.
i changed the ignition switch relay and it fixed it.

not sure if that would affect the idle too, but i am guessing that the car turning off while driving is the bigger issue.

Wow thanks mate. Yeah more concerned about it turning off while driving.

No probs.
Even though I no longer have a Honda, I may as well still use some of the knowledge I have built up over 11 years of Prelude ownership. (Between a 2nd gen and a 5th gen.)

Cleaning my IACV fixed this issue on my 5th gen

Is the idle problem only on cold start up or when the engine is warm too?

[Squalled]

Both. I think it could be a dirty AICV possibly as I've heard that what can happen.

Clean it, takes 10 mins

[Squalled]

Where about's is it on the throttle body? What would I use to clean it? Anything specific?

[RenzokukenJ]

In between the throttle body and back of the engine, attached to the throttle body itself

It's bolted on, with 2 small coolant pipes going to it

Use throttle body cleaner, spray the shit out of it

It will be all black shit inside

Also clean your EGR, google that one, that was another 10 mins, for lols start your car without it, sounds funny
