To close the book on this…
I tried the throttle reset with no success. In the meantime I ordered a new accelerator pedal assy. I bought amx1397s throttle body as a fall back.

Today I installed the new accelerator and it fixed the problem. The CEL turned off as well. The most difficult thing about getting the accelerator out is removing the washer that is under the nut holding the thing down. I didn’t have a magnet skinny enough to fit in and grab the washer. I tried a few probes and screwdrivers but no luck. Then I took some really strong neodymium magnets and stuck them on a pair of tweezers. There was just enough Mag strength in the tips of the tweezers to lift the washer. Also, it’s an awkward reach which didn’t help. After getting that out the pedal comes out easily.

I’m back on the road again. Thanks to all that chimed in.
