- 2002 Explorer 4.6 Limited
My 2002 explorer 4.6 is having issues with a high idle. It is a smooth idle around 2000 rpms(in park/neutral) even when engine is warm. No CEL is present. Last night I pulled the engine cover off and used a whole can of starting fluid to check for a vacuum leak but couldn't find anything. I have access to a genisys scan tool so I can pull a data-stream but not sure what I should be looking for. Doubt it is related, but last fall I had to replace the intake manifold(dorman) it had developed both a coolant and vacuum leak. I had also replaced the IAC valve(motorcraft) just prior to finding the intake issue. And also replaced the rubber inlet hose to the IAC valve(was leaking).
Explorer was driving great for a whole year after all that work and now the high idle is back. It has about 193k, runs like a champ other than this idle issue!
Thanks for your help/advice, DAVE
