Sounds like a tuning issue, not the throttle body. For one try and get your obd plug wired. What is the actual spec on your car. Its a lt1 swap? Or an lt1 pcm? What year? Who did your tuning? Seems like is something with the vss in relation to the idle decay
Also, 1000 rpm idle is high. No massive vacuum leaks like the egr at the back of intake?
