"Reduced Engine Power"

Haven't had the truck even two weeks and it's in the shop with an engine problem. Took it upstate NY (I'm in NJ) on a 4 hour trip one way. There and back no problems. Get on the NJTP yesterday and my display says "Reduced Engine Power" with a wrench, but no check engine light. Truck reduced speed down to 30 MPH and wouldn't let me go over 40 MPH. Drop it off at the dealer this morning. Has anyone else had this problem? Any idea's on what would cause the "Reduced Engine Power" to pop up? Thanks for any help!!!

Well, it's been at Ford now for 4 days, and they've been running diagnostic testing and other tests on it since yesterday, still no answer as to why I have "Reduced Engine Power". Has anybody had this problem before?

Thanks!!!

Is there a usual cause for Limp Mode? or can it one of many things?

Just got off the phone with the dealer and he said they found oil in the fuel. Right now they are in the process of pulling the valve covers off to see where the oil leak is coming from. A tech is suppose to call me back shortly and give me a more detailed update.

Just received a follow up phone call and they told me that the error code coming back is that the oil is overfilling. They said that the fuel is dumping back into the oil. Right now the valve covers have been removed and they are looking for the leak. Anyone had this problem? Is it a major fix?

Thanks, I will update this thread as info comes in. From what I've been reading sounds like a bad injector. It's a little disheartening, I've only had the truck 3 weeks, and 1 week of that time it's been in the shop. Thank you for the responses.

UPDATE: BAD INJECTOR

Just heard back form the service department, they told me that one of the injectors is dumping fuel directly into the crankcase. The new injector should be in tmrw. They will replace it and run the tests all over again from the beginning. Hopefully that will solve the problem. Does anyone have any experience with this problem?

My truck just started the "Reduced Engine Power" yesterday and now I'm wondering do I really have to take this in to the Ford dealership for repairs?? Or is there something I can do to save money and do it myself?

Any comments, advise or suggestions are greatly appreciated.

Thanks!
