Need Help! Can't get anyone to work on my F53 6.8 engin

do you have road care, aren't they supposed to tow you to a shop that works on motorhomes?

I have not checker the fuses. My alternator was replaced a month ago. I have though of a connector coming loose. But I am in Florida and the motorhome is in Georgia.

Have you checked the ECM fuses?
have you had any work done under the doghouse?

I have cleared the codes. They come back when I start it.

Well, stuck, fcked, broke down vs a bunch of whining about how hard it is, or not responding to help if you’re the OP, I know where I’d be….trying to get back on the road and forego another tow bill and a bunch of downtime.

Easy on a truck, not on a van chassis. On the van chassis the throttle body is under the upper dashboard. The mobile mechanic climbed on the bumper to reach it. Don’t know about Class A accessibility. Likely under the doghouse.

I had a bad throttle body on our V10. I found a mobile mechanic who fixed it in the storage area.

The failure appeared suddenly. Did a trip, stored RV at storage area. A month later went to pick it up for a trip and it threw error codes. Ran the ScanGuage and it said it was in limp mode and throttle plate was stuck shut. Couldn’t drive it anywhere being stuck in idle mode with a max of 1000 rpm.

Mobile mechanic used his diagnostic controls and said the throttle plate motor was working correctly to move the throttle plate, but the position sensor was bad so the position could not be measured. The sensor could not not be replaced separately so it required a new throttle body unit. Mechanic was able to replace throttle body from the front so didn’t have to open up the doghouse.

Good thing ours didn’t die on the road, I can imagine the hassle. Hope you find a competent place to work on your rig soon.

did you clear the codes so it maybe driveable?

I would second enblethen. Try clearing the code and see if it is driveable. Or can you see something obvious that makes you say nope it needs to be towed?

I had a fuel pump in my truck go out in Cordele. The guys at Mavis tire were super nice. I doubt they have room to get a class A in, but they might be able to point you in the right direction.

There are 3-4 RV dealers probably an hour north in Byron, and a couple about an hour south in Valdosta/Lake City , if they can't do the motor work, they may be able to point you in the right direction.
