I am running the stock ITR map on my car. It is running beautifully except for the idle... On startup it idles at 2k rpm and slowly drops. However, If I drive the car some and come to a stop, the idle oscilates up and down inbetween ~1,500 and 2,000 rpm.
Reading the General Info - Idle Guide it looks like changing the TPS, idle bypass valve, and timing and fuel affect the idle speed....
If it only oscilates unitl it is FULLY warm, what would that indicate that I need to change?
My last S300 tune I did not have to change the TPS or idle bypass valve; it ran flawless.
