TL;DR: Watch video links
I own a 1994 volvo 940. A few weeks back, it started giving me some issues. I first noticed something was wrong when I went to drive it and it wouldn't start. It would start normally if i turned the key on and off about 10 times. I assumed this was a fuel issue and that i had to prime the lines before it would start. I drove it for a day or two quite a bit(50+ miles), and, while it continued to give me trouble starting, it ran fine once it was going. I pulled into a parking lot and was idle/coasting to a spot when the car sputtered out and died. I restarted it, and it seemed only 1 or 2 cylinders were firing, it was running REALLY rough, under 100 rpms, and throwing the engine around. I parked the car for about a week before bothering with it again.
I went to pick it up and it started fine. I got it to the end of the parking lot before it died, and wouldn't restart. Went to try to get it again a few days later, and drove it about 3 miles home. While driving, the tach would sometimes drops to 0 and bounces back up, sometimes it dies(as seen in the videos below). When i start it back up, though, it turns over once or twice and whirrs right up, making me think it's not a fuel related issue at all, but electrical or a sensor.
It sat for a couple days at my house, when i went to mess with it i cleaned the battery terminals/cables, and found 2 loose plug wires. I popped em back on and drove the car about 10 miles with 0 issues. On the way home, it died multiple times and was idling weird.
Basically that brings us to now I took a couple videos of the instrument cluster with the car running.

In this first video(sorry for sideways), the car had run for a few minutes before I took it. It ran pretty fine until it warmed up. I decided to throw some random revs at it, and it died whenever I pushed the gas quickly.

Right after the first video and prior to this one, I ran the car a few times. It started off idling at a normal rpm, about 900. I pressed the gas pedal as quickly as I could(not depressed very far, just very quickly) and the car immediately died the first two times I did it. After this, however, a couple times I did the same thing again, only when I pressed the gas quickly, the rpms were going up and sticking for a second, then dropping back down. I did it again, and the tach was sitting right at 1.5k. I then restarted the car, and took this video.
There is no check engine light on and it's not throwing any codes, but she has given me some problems in the past. I haven't noticed it dying while not at idle, but the rpms have dropped to 0 and bounced back up about .5 seconds later while accelerating.
So for a while, especially during the cold months, I would be driving and either after accelerating or driving on the freeway for a couple minutes, it would run rough at idle or even die. Intermittently, for about 8 months(?) I will loose power while accelerating through turns or from red lights. I replaced plugs(which were pretty fouled), wires, cleaned throttle body, maf sensor, etc. This seemingly fixed the problem, but now I think the current issues may be related to what was happening before.
Thanks for reading. Please respond with any advice/experience/links/info you may have which would help!
