Regarding that very pesky code -11 I was getting; I fixed it. Darn thing was the contactor and I tried everything else. From throttle switch replacement, cleaning wire connectors and even emery cloth on the contactor(while assembled). But today I went at it with the dash off and driving it around trying to trigger it yet having it trigger on its own. That is until I stopped it, put the foot brake on and gave it throttle while trying to force the -11 and throttle cut-out. Nothing until I slapped the contactor with my hand!
Took the 4 long screws out, put a file across the outside 2 contacts and then figured out a way to get a file onto both the inside contacts while in place. Reassembled and slapped the contactor silly and it would not throw a -11. Drove it hard and fast around the block and smooth as could be.
Now I know so in 5 years, if it does it again, I’ll know where to start this time.
