Where I live most auto parts store will check the code for free. The code usually does not tell you the exact solution to the check engine light but usually point to the system which need attention.

I need to know the firing order of a 2011 Mercedes E350 class. Please show diagram

You did not say what year the truck chassis is, so I will give a generic answer.
If the throttle position sensor was at fault, the computer should set a trouble code. So if there are no codes, I would question the fuel pressure or venting in the tank. Fuel pressure could drop off to just enough to keep the engine running but not have enough to rev up. Or the pressure vent valve in the tank may not be working and the tank could be building up a vac. Its also possible the fuel filter is clogged up enough to restrict fuel pressure or volume.
You would need to check base fuel pressure and the condition of the gas tank when the problem occurs which could be tough to do on the road. You could take the gas cap off and see if it will rev up to check the venting. That will probably turn the check engine light on due to the tank being open with the engine running.

that is your ttc solenoid . it is your torque converter lock up solenoid. it is located in the transmission ,and to get the it you have re move the side pan on the transmission on the drivers side

Take it to AutoZone for a free diagnostic scan. Your local Ford dealer will charge you $100+ for the same scan.

It sounds like the idle control valve and/or the mass air flow sensor. The scan will accurately pinpoint the problem.

The service engine light is the check engine light. Different name for the same thing.

go to autozone and get the codes. they will test for free.

I also have a 96' shasta RV 26' E350 Ford chassis... ABS light comes on whenever it feels like it. We have 20,000 miles on the RV. We love the Motorhome but am constantly worried about the light. Our mechanic said not to worry about it.. Not worth the expense to fix it. anyone have a clue? grandmanomi
