My idle has decided to run amok. My Jeep mechanic guru has swapped out the "idle air control motor" and it seems to make no difference. The engine will idle properly in the 6-700rpm range for a while then it will surge to anywhere between 1000 and 2000rpm and remain there indefinitely. The only way I have been able to limit the rpms to a manageble range is by blocking off a major part of the "idle air control passage inlet" (ref. page 14-45, SERVICE MANUAL , JEEP WRANGLER). Can anyone suggest a procedure to isolate and identify the problem? tia dw
