Yikes, Scepter Won't Go!
As I had just finished some work on the coach and I was starting down my 400ft driveway and the coach would not go over an idle, give it more throttle and it would not gain any rpm's. So, I backed up and started forward again, the same result.
Now for the rest of the story!
I had just repacked the front wheel bearings, so guess I better look there! Well long story short, I had pulled the ABS sensors out, cleaned them and didn't push them all the way back in, I wanted to wait till I was done with the repack. I remembered as I took off but had no idea it would keep my from getting up to speed. Just didn't want to crawl back under coach till I got done. I think I'll look to see if the ABS can be disabled in case a sensor goes bad. It would take along time to get anywhere at 5 mph!
Thought this might help someone in the future.

After checking and re-seating your wheel sensors, I would look at the throttle position sensor is disconnected from the engine ECU. The sensor is part of the throttle (often called the gas pedal, but we know it's not gas). It could have been pulled loose from a connector, either at the pedal, or somewhere along it's path to it's destination. Physically finding and following the wire may lead you to the problem. I suppose it also could be a bad sensor on the pedal, but probably not.

OK ; for the life of me ; I can't think of an electronic link between the ABS module, and the engine ECM that would shut down throttle control.
JMHO: You might want to run a scan on the engine and trans controllers to check for stored fault codes, that aren't turning on the CEL.

Well, it made no sense that it would do that, but, pushed sensors in and all was well, took 80 mile trip with no trouble. Never happened before, and if it does again I'll post a new trouble on the site.

I should have said, I backed up to shop, pushed sensors in and coach was fine. Went for a ride with no trouble. The sensors were pushed in an inch or so, just not all the way at the time of trouble.

Does your coach have ATC? I suspect that the system though that the tires were not turning and depowered because it thought there was no traction, though the ABS system may be able to do that as well...
