Unhappy RPM surge/jump forward

Hello
Newbie here. great website I have found. I dont feel so alone anymore!
Just yesterday RPMs jumped slightly and the Truck jumped/ lunged forward enough for me to notice. We bought this used about a month ago and have not yet had any problems. I was going to take it this weekend to have an oil change/fuel filter/oil filter change. But I am heading to dealer tonight! I know its not much info for you guys but is there any thoughts ? Truck seems to have plenty of power even though the Excursion is one heavy beast. The CEL did come on of course if that helps ?

I bought this for my wife to haul around our two kids and dogs and travel with. She babies this Truck and does not drive it like a 16 year old male might...
I am certainly not experienced like you guys but love the diesel for durability/strength and longivity..or so I thought??

Anywords from you fellas ?

Year and miles would help. Well to start with you can not baby these trucks or you will have trouble the EGR valve will plug up on you and the vains in the turbo will stick so about everyother week after it warms up you have to drive it like you stole it, and you need to use a cetane boost in the fuel to help keep thing clean and do not idle them to long and only use Ford filters These 6.0 need gauges or you can get into trouble.

I would get a new EGR valve and get it install if it has never been cleaned look here how to clean.

You need gauges!!!!! The big thing is the difference in EOT-ECT the max is 15 degrees driveing 55-60 on the freeway if you have more than that your coolers are plugged, also need a fuel pressure gauge because under 45 lbs at WOT you will kill your injectors mine with 17k on it at WOT was 44 lbs and 50 at idle installed reg kit now 62 idle and 58 at WOT, get a coolent filter on and do a flush on the coolent and install ELC coolent. Big shopping list.
