[QUOTE="gyates, post: 979370, member: 69134"] I am looking for ideas on this issue. I am having some erratic idle issues with my 4.0 SOHC. So far I have replaced the IAC valve and its gasket. At time it idles perfectly at 750, but at times it idles lower. Ac on or off does not impact this. I can not find any pattern to when it idles good and when it idles low. I do not have a CEL so no diagnostic help from the computer. Could this be the beginning of the famous PCV elbow failure? [/QUOTE]
