Dear mphilleo,

Hope you're well. The Idle Air Control Valve has failed (IACV). Installation of a spare, "known good" IACV, should produce a steady idle at 600-700 RPM. The clue: cleaning the IACV made no difference and clamping the hose to the IACV corrects the problem.

Hope this helps.

Yours faithfully,

Spook
