I would just add, inspect thoroughly or replace your plug boots.
I had issues years ago with high boost bucking and it was finally tracked
down to a very hard to see split in the silicone boot of one of the wires. I
put black electrical tape over it and the problem went away. I then replaced
all the connectors at STEALER prices. That was before I knew of "The List"
