Got a 94 zj and my on board diag is flashing on the date and time with the windshield lighting up none of my buttons work to set or reset or select anything.
I'm thinking it has to do with my surging.
Pls help
What will it effect if I unplug it completly????

 

Check Your relays underneath the Glove Box.

 

mine started doing that awhile back and now the whole center of the dash is dead (VIC, clock, radio). I'm in the middle of a fuse/relay hunt myself and thus far can't figure out which is causing the problem.

 

I unhooked it for about an hour and then repluged it and stoped flashing I'm still having the surging tho aroung 50 mph my rpms start surging
