If those all check out, its possible the O-ring/gasket is bad and may need to be replaced. Its a simple procedure, just two bolts. They hard to get to, but it can be done with a 1/4 ratchet and an 8mm socket.

Thank you to the original poster. I am having some of these issues in my truck and this ought to be very helpful in the hunt for the "rough idling" culprit.

Can someone tell me if the pictures of the ECT sensor are correct in this??? I have that same sensor on my 2000 5.4 but everyone keeps telling me and everything I look up says I don't have a coolant temp sensor. And I have a cylinder temp sensor instead. So What exactly is that sensor on the front right side of the block? if it is a coolant temp sensor anyone have a part#
If you read my post about my issue you will understand my questions here now. https://www.f150forum.com/f6/2000-5-...issues-257614/

Yes, the picture is of the cam sensor, not the ect. I mislabeled them when loading them.

Wouldn't you know it, I am having problems/codes with my o2 sensor, I'm a million miles from home and that's not covered as yet. Wonderful.
