Im have a problem in my 2007 fx4 5.4 every so often when I step on the gas to speed up it will shudder the rpms dont go up and nothing on the dash goes off but it acts as if the truck lets up then goes again then lets up and goes again it has 86,364 miles on it

Maintenance wise, what have you done with your truck? At that mileage, I'd make sure the plugs and O2's are replaced, throttle body and MAF cleaned, fuel filter replaced. All those could possibly cause your symptoms.

I just got it from the dealer on monday and they said they changed the oil and no lights on the dash light up when it does it Im gona call the dealer on monday and see if the dealer had changed the plugs or not
