coming home from the dentist car is running fine, it starts to rain, well pour and as usual i tense up cause im drivin the camaro, i get home and park

later i start the car and up and head to my girlfriends and the speedometer is jumping to anywhere from 5 to 105 mph, my ABS inop. light is on and the red check guages light is on and the radio is randomly flickering. the car is running absolutely normally though, i checked all connections and nothing seemed to be loose or out of place

any ideas?
the speedometer has always been off but never like this, and i installed new wheel hubs (where the ABS connects) recently

 

Take it to Autozone or O'reillys and have it hooked up to a code reader and see what it says. And btw I'm digging your headlight conversion. I'm planning on doing the same thing with my car.

 

yep get her scanned for trouble codes and let us know what they are. does sound like a bad connection/wire somewhere. hopefully the codes will give a indication were to look.

 

Yep, codes will help but also check grounds on the car to make sure none of them are rusted up. There are several of them located under the hood and around the fuse boxes.

 

Since it seems nobody can actually provide an actual suggestion to what this could be, I will do so by providing what fixed this issue for me. (even though you might have fixed this issue already, this might work for someone else; for future reference)

Seems like the ABS module. I had a similar problem, got the part @ a junk yard and like magic fixed those issues. Most, if not all ABS issues (in any car) are related to the module itself which I'm sure you know controls your Anti-lock Brake System
