v10 skipping
just bought an 01 f350 v10, 40,000 miles,plowing beast, anyways when taking off truck seems sluggish, give it more gas as its fine. At idle there appears to be a skip. There is no check engine lights on,could it be coil pack or even maybe fuel problem? Have done plenty to this beast to get it close to perfect and this motor issue iis it. Any ideas ?
thanks

I always recommend purchasing a scan tool , they are relatively inexpensive and will answer many of your questions .
These are the type of questions , that are difficult to answer on the web.
What Redford said is a good place to start, along with examination of all vacuum lines .
I doubt the coil packs are going bad at 40k miles, but keep in mind the boots are rubber , and will dry out and crack, causing the spark to arc to the head instead.
Boots with springs are around 6 dollars each at most stores.
Always use die electric grease on these parts when changing the boots and when changing spark plugs .

I would change the fuel filter since sat it apparently sat. Cleaning the maf and IACV as redford said may help as well. I ran seafoam through the booster to clean my IAC and it helped the surging idle temporarly. A common vacuum line that leaks is the elbow from the throttlebody to the pcv hose and valve. Can cause lean codes and hesitation as well.

It is rare for the coil packs to go bad with that few of miles.
Personally I would check the boots , more chance of that drying out and arcing to the head.
FYI , you can check these coils , the same way as a conventional coil , to determine their condition at rest.
The standard test with an ohm meter , will not verify a bad coil under load.
