2006 Powerstroke rough idle

[AlbertanF350]

Hey guys recently my truck started idling different rougher is all i can describe it as. inside it feels like theres a vibrating massage thing in the seat haha and things rattle and it never did this before. Also it seems like sometimes it cranks a litle longer before starting but i might just be being paranoid. It doesnt matter if its warm or cold it idles the same and doenst sound any different when your outside the truck. It doesnt smoke and it still drives fine and doesnt seem to be down on power. its very wierd and i guess il have to get it scanned eventually anybody know what that would cost? (just the scan at ford)

For a scan at Ford your probably looking at around a 100 dollar diagnostic fee. You could go down to advance or napa or somewhere most of those places are willing to scan for codes for free. However you may have an issue that is not related at all to a code. For one couple months ago I was having a rough idle and some slower starts on my truck and it ended up being the fuel rails were leaking at the plugs in the rear. Since it was leaking the revs would move slightly so that it would still deliver the same amount of power, thus it vibrated some. The vibration and rpm surging were not always noticeable and some days were better than others. So just an idea there sorry for the long post.

no prob man haha that almost sounds exactly what happenning no change at all in the truck except for a vibrating idle. any way i can check this myself (visual)? or how did you fix it?

did you ever have any luck on finding the issue with vibration at idle. mine is a 03 and doing the same thing as you explain and i cant seem to pin point the issue. it just randomly started the rough idle one day. very agrivated with it

[AlbertanF350]

nope its still doin it might take it to ford this weekend. it is very strange there seems to be nothing else wrong at all

Mine has a rough idle sometimes too??? Like it'll just start and stop at random times? Drives fine etc...

[strokin211]

let me know what ford tells ya if you would, im curious. i had my ford mech look at it and he has no idea what it could be he dont seem to think its an injector. you still been driving yours with the vibration? and when you come to a stop light and are in drive does it seem to do it worse than what it does in park?
thanks

Yup thats exactly what it does. I dont have money to throw at it so im probly just gonna sell it and buy something that i dont have to worry about all the time im not sure yet

Check the dummy plugs at the end of the fuel rails its what Ford changed on mine that fixed the issues. I couldnt really tell you what exactly led them to that being the issues as I am still under warranty and they dont communicate to well. I would assume though if they were bad they might be leaking a little bit of fuel out of them, which is why the engine is revving to provide the same amount of fuel to the injectors at all times.

what do you mean by dummy plugs on fuel rails? how would i get to them to check? and mine dont so much rev up and down it just vibrates when at idle and in drive and stopped. dont make much since to me but drives out fine. all help is appreciated thanks
