Thank you guys. It’s always good to have consensus when you have to spend a couple hundred for a part. Curious, has anyone ever attempted to diagnose the position sensor? It’s probably a variable resistor of some flavor, right? When the variable resistors start acting up in my guitar amps I clean them with electrical contact spray and they are good for another 10 years.

I will get a new pedal on order but I will see if I can determine what is wrong with the old one.

Edit: the service manual says the position sensor on the pedal is a Hall effect and magnet. And it says there are two, a primary and a secondary. The system compares the two signals and if #1 is different from #2 it switches to #2. Maybe that becomes limp mode which acts like what I and others have described as slow acceleration.
