Tomorrow is the big day and I'd like to thank you, Art, Trevor, and others for helping me get a plan of attack together. I did cure the bouncy speedo thing already. That turned out to be a loose connection on the back of the instrument cluster. I'm getting a more consistent temperature reading now as well . It used to say the engine was chilly most of the time. Now it sits in the middle. I wonder about the ECU. I did use it to pull a code 2 months ago for the speedometer sensor thingy. When I removed that cable from the top of the tranny it was clearly shot. It's lucky the car was still running because they typically don't if that wire is compromised. Anyways, after I fixed it and cleared the codes everything was good. I will clean up all the wires, that 25 amp fuse, the grounds that Art suggested, and check for Vacuum issues that Trevor mentioned and report back.
