05 Taco acting goofy, Electrical problem?

Immobilizer?

Battery terminals loose, acid covered, oxidized posts?

 

Alright... everything has been cleaned. Waiting to see if it does it again. Intermittent electrical problems have always been my least favorite!

There are 2 other things the truck does that is goofy that I just didn't think of (have always done these); the dome light does not come on if you open a back door, and the volume on the radio's dash knob doesn't work. When you spin it you never know what it's going to do, sometime go up or sometimes go down. Luckily the steering wheel control works.
