I"m working on a 04 360 prarie for a buddy, and I can't get it out of limp mode. I've done the plug swap 10 times at least, and pulled the cover and made sure the switch was at the rear, and I can't get it out of limp mode, what else could cause it to stay in limp mode? The check belt light keeps flashing, the 2 wires ohm out so it shouldn't be the switch.
