Hello,

I got my TB machined 3 months ago, it worked ok in my 98 ITR.
Yesterday iīve installed it on my friend 99 ITR and the idle was very irregular.
We could adjust the TPS only to .415- .420 max. Wy canīt we just raise it to .450 ???

The part numbers on the sensor are the same.

Thanks,

Pinota

 

I have a machined itr tb. The idle is fine, about 800-850.

I did previously have a bbk 70mm and I had a lot of fluctuation between 900-1500rpm.

 

There is an adjustment screw on the upper left side of the ITR throttle body that is covered with paint. Remove the paint and you can make adjustments that wil help with the idle.

When you say machined what exactly did you do to it ? If possible a pic please.

 

when i put my bored out tb in.. it took a lot of tweaking of the TPS and IAS.. also don't forget to reset ecu (well i'm not sure if this helps but i had to because i kept getting a cel)
