I have a '91 SHO. I was doing about 75mph in 5th gear today when my RPMs drop from around 3,000 to 2,000, even though my speed and gear didn't change. I didn't hear anything out of the ordinary either. I smelled something hot so I pulled over. Saw no signs of burning. The smell could've been another car. Drove it some more. When the RPMs drop, the power drops way down. The RPMs drop randomly.

I'm sure it has something to do with electrical, because I went to jump start the car the other day and mindlessly put the jumper cables on the wrong posts. A wire from the starter sylonoid started smoking, so I pilled the jumper cables off ASAP. The car's idle dropped and bobbed once, for about 15-20 seconds the next day. And now this tac problem.

Any ideas what might have been damaged to cause these weird symptom
