'04 F-250, 6.0L Idle funky?

Hello, I searched around the forum for a solution and found that perhaps the engine harness is causing my idle to lurch down (misfire it sounds like) and then back to idle.

When the truck is moving it doesnt do this, only at idle youll hear it wanting to die every few seconds.

Where exactly is the engine harness on this year truck? it has low miles, 50k or around there.

Please help, took it to the dealer and they said it was the oil, they changed the oil and problem persists.

Thanks

- Dan

It may be wetstacking (I think I'm using the right term). Does this only happen when you idle for a long time? More experienced guys would know a lot better than I would but I did ask a similar question on here and that's what they came back with. If anything this will be a good bump for you and it may catch a tech's eye.

Hello, what is wetstacking? No it wont do this after a long idle, it just does it at idle regardless of how long the truck has been idling. i.e at a red light or anywhere i come to a stop.

It has that choppy idle, kinda hard to diagnose i guess.

Wetstacking, from what I understand, happens when the temperature in a cylinder becomes too cool too ignite all the fuel. This can happen when you idle for a period of time at low RPM.

As far it happening all the time in your case, I have no clue. Hopefully a tech can help answer that one. Hopefully you are still under warranty and can get Ford to fix it.

sounds like a fuel problem to me. Do you use a fuel additive like ps? Solved my neighbors 6.0 problem with hard starting and rouge idle, smoke.
