I have a 2005 Xb and I am trying to figure out the best way to increase the idle. Can anyone show with pictures if they have them to increase the idle please?

 

is your idle air control valve bad?

 

No its not bad at all. I just want to increase my idle by a few hundred rpm.

 

The idle air control valve can get plugged with carbon - which is one reason the idle speed can drop. If you really need to up the idle speed, there is a screw on the throttle body that will open the throttle plate a bit. However, at some point it will throw a code - so relief will only be temporary.

 

Find the throttle body (just follow the throttle cable toward the engine) then you will see a nut with a threaded rod coming out with an Allen head hole in the middle
should be right next to the big spring. Just loosen that jamb nut and turn that threaded rod in until you like the idle and re-tighten the jamb nut.

Sorry, no pictures. I traded my 06' TCM Box for a 2015 tC2.5 RS9.

 

How can you check to see if the idle is bad? Right now my idle in drive remains at about 600 rpm. When I have the headlights on and sometimes the a/c on at a stop the rpm cycles up and down. Is this a normal thing on the Xb?
