As said in the title my car idles high. It will idle normally when I start up but as soon as I start driving it the RPMs jump to about 1500 and sit there sometime it acts as though it is stuck in the warm up cycle where it varies between 1400 and 1600. Does anyone know what is wrong wiht my car. PLZ help.

you and everybody else. mine's doing it. vacuum leak, bac, and tps are the biggies. generally a vacuum leak and they are a bitch to find. goodluck and check down the page for other idle threads.

 

my TII does that too! when i turned the screw on the bac all the way in it stopped bouncing... haven't had a chance to test stuff out... i replaced most of my vacuum hoses with silicone ones beforehand except a couple that's from the IC to the bac/aws mechanisms, and the TID (all of them have minor cracks at the connection points), did the TB mod.... just have to fix those minor things and see what happens then... too lazy to do anything heheh

Mods should sticky this

 

A crack in the TID was causing mine to idle around 1500

 

mine does that when its warming up and then after a few minutes it settles at 1500 and then after a few more minute it goes down to the stock idle speed of 750

 

Here is my saga
