I have a Hyundai accent 2000 model, and I think my Idle speed is bit high (Around 950 RPM ) how can i adjust the idle speed? Other cars mostly japanese ones have a special nut on the EFI unit to change the idle speed
Mines an 04 and my idle is at between 794-805...just sorta jumps around that ballpark. If i could lower it to 760-790 that wouldbe cool...give it a low rumbble with that...heh heh but I'm sure its not good for the car. Anyway
Check the throttle butterfly...see if maybe its stuck...do the screw thing and also the throttle cable...could just be that theres a minor stuation keeping it from being closed all the way...also one of the vacume lines may have small leak.
all in all I agree w/ Wilbur...why bother as long as you pass emissions right?
