Weird idling and grounding issues.
Today my 92 took a crap. First a bunch of lights came on my dash.. battery, ebrake, low water among others came on. I drove it home a few miles and when I get home it has a crazy idle loop going to like 2k then back to under 1k. I turned car off and disconn car battery. I turned it back on at it has the same idle but the weirdness continues I go to put it on drive and it takes off like my foot is on the gas and even when I brake it seems to be accelerating at all times. My first taught was tps but what else could it be?? Thanks in advance for your recommendations.

First guess is battery voltage getting low, or bad connections battery. Maybe alternator not putting out, maybe fusible links corroded. Get that checked first.
Not many scan tools work on the OBD1 stuff.
OH and also weird things can happen when the trunk hinge wiring is messed up, search here for that one too. Don't jump into TPS and all that when the dash lights weird out that is an electrical supply issue when everything electrical goofs up, not just one item on the engine.

Until you've got your voltage confirmed good, I would not spend time looking at other things.
