Here's the story. I drive off the highway and thought that a car next to me had really loud base music, since my car was shaking. I realize that it's actually my car, and that the engine is almost "jumping". Like it's trying to rev forward and would probably hit the car in front of me if I hadn't been braking. I noticed at this point that an extra light was on, it was the ECT POWER switch that is below and to the left of the gear shift. I had never turned that on before, so I turned it off thinking that was the cause of the shaking. I drive a little more and notice that the acceleration isn't really working, it's very weak and I could have pressed down the pedal completely and it wouldn't have moved. I manage to get it to a parking lot and turn it off, wait for a while, then turn it back on. It seemed fine so I test drove it a little ways. After about a minute, the engine started making that shaking feeling again (the ECT PWR switch is still off at this point) and then suddenly my dashboard lights flash and the power steering stops working and the brakes became really hard to press. (I'm thinking the electronics stopped working? However, the lights were still on in the dashboard, so the battery isn't dead.) At this point, I park it and get it towed home, since I'm not driving without brakes. : ) In any case, I was wondering if this is something easy, like I'm low on some sort of fluid, or if it's something I need to take it to the shop to get diagnosed. Any help would be appreciated!

Sounds like the engine stalled when all the lights came and the p/s stopped working. There are alot of possibilities here. I would check the battery and charging system first, along with having the vehicle checked for diagnostic trouble codes. If you can get any codes from the vehicle it will help me point you in the right direction.

Thanks for such a quick reply! I got the trouble codes like you said, there are two that show up: 63 - Open or short circuit in no. 2 solenoid valve

67 - OD direct clutch speed sensor signal malfunction

Is this perhaps just a fuse? Or do I have to go get it professionally checked out?

Start with what Marv told you.

I have a 96 with the same codes and they are trans codes and have no relation to your issue.

I would start with a fuel pressure check. It sounds like basic engine
