PalmSpringsE534.6 is on a distinguished road
I had the same issue with my throttle body at one point. Try this...disconnect the Throttle Body connector. Clear the codes from your rig...and fire it up. It should start using a default algorithm so the response won't be quite as good. If it does start up and run well (as compared to what it's doing), reconnect the TB connector with it running. Shut the car off and re-start. Totally resolved my issues. For some reason, the TPS communication with the DME didn't "refresh" appropriately until I did this procedure. Then I was off to the races with full throttle and nice smooth idle.
