1993 Lexus SC400 Questions

My car is acting strange it's done it before. It's like the car has a mind of its own. I used to put cheep gas and it started to shake and exhaust smoke would pour in my cabin. So I changed to premium after the mistake I made. So it ran great for a month but just recently it started again...

The speedometer bounces all over. It registers 80 when I am doing 35, and it will stay at 40 when I am stopped. I am at a loss why it is malfunctioning

not sure why it wont engage?could it be a relay holding me up?maybe electrical?not sure where to go from here?

I'm on my 2nd SC and have also had a '98 GS400. Fabulous cars - my '92 SC400 with 247K miles didn't run much different than when I got it with 106K. My '98 GS400 probably saved my life in a crash and now I have a '93 SC400. Love 'em!!

bought an sc400 right after graduating high school, this is my first car and I love it, im keeping this car 4 a while
