Reattach the factory ground and see if that helps. If you grounded somewhere else it might not be a good location.

The factor ground from the negative battery terminal is still there in the second picture. Do you mean remove the new grounds and see what happens? Will this be ok to start the car without those two grounds

You didn't unplug the vehicle speed sensor while you were fooling around there did you?

Sounds like the ecm didnt reset or something happened to it.

Check your fuses, make sure you didn't pop one when you were hooking/unhooking the battery.

I was just coming back to say this. I blew my battery fuse one time and it made my car act really weird until I figured out the problem.

no that should be located way in the back of the engine. Theres a green alternator plug that I unhooked but plugged that back in

I checked the exposed fuses with a dmm for continuity they read fine. I didn't however unplug the massive fuses under the hood.

[Impious 1,476]

I would check them all.

something about the E.L.D. re-adjusting as to why it ran horrible on first startup i'm going to drive it around and see what happens.
