1969 Dodge Dart Engine Stutter

Hello everyone,

I hope I am posting this in the right place. First time poster here.

So, I recently bought a 1969 dodge dart. It has 65,000 original miles on it and I am the 3rd owner. I am having a bit of trouble with engine starting / stutter / stalling. I am going to get into a bit more detail about the symptoms and I was hoping some of the experienced folk here could help me narrow in a bit. I know a lot of these symptoms can be a part of a wide array of issues. I am hoping to create a list and trouble shoot one thing at a time but I just don't know where to start.

The car recently had a backfire that blew the muffler. I had the muffler replaced and a short repaired in the engine bay. That got her running again. But, now I am suffering engine stutters / failure to start issues.

If the car sits for awhile then I can no longer start the car, I have to get it jumped. When I first get it jumped, it runs great for a bit. The moment I turn on headlights or windshield wipers, the car begins to rattle and stutter. When I am driving, as long as my foot is on the accelerator it runs great. If I am at a stop light, the longer I sit there the more the car starts to rattle and sputter like it is about to quit. I have had both the battery and the alternator checked at AutoZone. Both checked out. I have noticed corrosion on the battery leads, green film, I am assuming because the wires are copper.

Any advice? What should I look for and where do I start?

Thanks
