Hey, I had issues with mine when I first got it. I tried to tinker with it, in the end I ordered a new one from Autozone or Napa. The new one has two adjustment screws. I had a friend of mine adjust it for me. I had problems getting it just right. It would stall at stoplights. It seems to idle low now but its the only rpm that will work in any condition for the 360 and auto trans that i have.
