96 Es300 Idle Speed At Start

Lance Orton · November 13, 2006

what should the idle speed be (in rpm) at startup on my 96 ES300? if my resource is correct, it starts at about 1000 rpm for 5 seconds and then drops. but what should it drop to?

the idle air control (iac) valve got stuck so i bumped the idle a hair so i could drive the car until i could clean it. i'm cleaning the iac valve in the morning and need to know what to reset the idle at (yes, i forgot to look beforehand). thanks in advance.

Fix the IACV before you know what your idle is really at.

Never adjust the idle by the screw it is computer controlled.

well, the screw can definitely increase the idle. i'm working on cleaning the iac valve. thanks.

i couldnt help to ask, since obviously you know about the idle speed on a 96 lexus es300, if you knew what it should be for a 93 lexus es300. mine has been idiling at start up at close to 2000 rpms and comes down to about 1200 to 1500. after you run it for a while it drops to about 800 but it goes up and down. thanks, firer

That's normal.

Lance the WARM idle for the car is 750rpm. +/- 100rpm.

yeah, i've noticed that its WARM idle is at the first line below the 1k mark. i'm assuming that's where it should be given the computer is controlling it. but i have a friend that has the computer hardware/software to interface with the vehicle's computer and when he comes over later this week i'll know for sure.
