3FE.Idle spped/Throttle cable/ thud?

I adjusted my throttle cable when I tuned my truck. I got rid of the thud when I let off the gas, but my engine was racing at 1200 rpm in park. When I bafck it off to about 800 rpm the thud is back? What is the optimal idle speed? I tried like heck to get it at 1000 rpm, but gave up after tightening, lossening, driving. repeat, repeat, repeat. It now idles at about 800 rpm but the thud is back? Could It be my kickdown?
