idle problem when i hold the brakes

[ddpxxx]

yea.. it may be something electrical but im thinking the cooling temp sensor. This makes sense because this problem only occurs when the car is fully warmed. but electrically this also may make sense but hard to diagnose.

i really dont think anything is wrong because the car adjusts idle under loads, IACV etc so it will always adjust under different conditions. when the car is warm the IACV starts working to control the idle and the ecu comes out of a closed loop mode. the load detector on my si i read today is in my under dash fuse box but i think your good. we may just need to clean the IACV but i doubt it. even my old stock si i bought brand new off the truck in 200 with only an intake on it did the same thing brand new.
