Surge at idle

My truck has been surging since i got it a few months ago. Only did it rarely at first, but now it idles up and down all the time. I unplugged the ICP sensor while it was surging and it smoothed out. Perfectly smooth. I noticed a super lite coating of oil on the plug. Just replace the sensor right?

icp sensor

alot of times it is as simple are the wiring harness going bad. when surging condition occurs move harness wires around and see if surging stops. if it continues i would replace sensor, if it stops they sell replacement harnesses. I have a brand new icp sensor i would sell to you for 80.00 shipped.It is for 2004-2007 6.0s with production date from 7/19/2004 thru 12/18/06.

my truck was doing the same thing, brought it to the dealer and it found out it was caused by the cheap oil filter that I had used the last time I changed my oil. They put in a motorcraft oil filter and it was good to go. since then I am alot more caustious about what I put on my truck. Definately worth checking if you don't know what type of filter is in there.

napa filter is on there. I bought a motorcraft filter got it apart and realized what was up. I was in a bind and got another NAPA filter. I need a ford lid to go with the ford filter.
