My 93 Corolla's speedometer is acting bizzare. It is very erratic and even will go up and down with car running in park.
I just got it back from my mechanic who replaced the sensor (I hear there are two) but it still is acting up. I have to use the speedometer in my GPS while driving.
I also noticed the car (when I got it home) won't stay running. I found a broken (white) wire at the generator wiring harness (and green corrosion).
I believe when I replace this the "running" trouble will go away. My question is, does this electrical trouble affect the speed sensor(s)? If not, any ideas? I will call my mechanic in the morning but want some ideas.
