high idle on start up
high idle on start up
I have k proed k20a2, jrsc @5psi(street tuned)....when starting up it idles around 2000rpm untill it warms up...is it good for motor to idle that high on cold?! it all started when i first installed k pro! with stock ecu it was ideling way lower....
Re: high idle on start up
It should not idle that high. Check for vacuum leaks first, then clean the idle valve.

Re: high idle on start up
no vacuum leaks and iacv is new n clean...
Re: high idle on start up
If you block off the IACV port in the throttle body, does the engine stall?

Re: high idle on start up
I havent tried that but i did buy a bolck off plate for iacv and disabled it with k pro and still....
Re: high idle on start up
i think its in the ecu, it was never like that before k pro, i have tried moving idle duty, changing idle rpm and still...

Re: high idle on start up
Car still idles high on start up but have a new problem! Unless car is let to warm up for 10 min before driving it dies every time the clutch is pushed in...It will not die while driving or when warmed up but I hit the clutch, it idles down and dies...2002 rsx s jrsc 9psi kpro
Re: high idle on start up
I have thesame problem, mine is at 1800 rpm approx.
How can we check for vacuum leaks?
All the tubes are connected to my cold air intake. I have not yet checked my IACV valve however.
But after 20 seconds it lowers to 1500 rpm.

I think he's suggesting that this would be a really good test. :)
I also had luck playing with the Idle Valve Duty Cycle Adj slider when my idle was high.

Re: high idle on start up
But why is this with hondata only then? Before i had no problems at all.
Re: high idle on start up
Remove your intake pipe and, with the car running, put your fingers over the iacv port inside the throttle body to block air going into it. If the car doesn't die you probably have one hell of a vacumn leak. You can also try spraying brake cleaner around the various fittings to see if the motor stumbles a bit.
