help with my grand cherokee

94 grand cherokee 4.0 6cyl

my display screen is saying my washer sensor is bad

the only problem i can say i am worried about is the surging feeing i get so often, while driving, if that explains anything.... its weird i was wondering what would cause it.

try NAGCA or Mallcrawlin.com. That's a fairly specific ZJ question and they specialise in them.
