I recently started getting a issue where when I slow down for a red light or taking a corner the engine will stall on me. It didn't happen when I got the car 3 weeks ago but the day after unplugging the battery to install a subwoofer the problem started. I've already unhooked the sub but the problem still persist.

I've also tried an idle relearning proces but I don't even know a 94 civic does that. Starting the car is a bit rough but once its running it runs pretty good and won't stall most of the time. No CEL in the dash either, when it does happen I can just hold the clutch and start it again with key. This is my first car so I'm new to all of this. I did find a loose connector close to the battery but I can't find anything about that and whether or not it has to be plugged in, you can see it in the pictures.

Model: Honda Civic DX EG3 1.3 L D13B2

Thanks in advance!
