Question about 1991 Chevrolet Lumina
My speedometer is way off it will say I'm going 90/100 when I'm maybe going 40. And you have to jimmy the turn signal thing to get it to turn on and usually hold it in place to make it stay on. What could the problem be?

Sounds like your speed sensor (odometer sensor) is failing or failed. This sensor is found on the tranny. Best to consult your local dealership.

There was a recent class action law suit settled with GM for this exact problem. You can google gm speedometer lawsuit and get lots of information. Unforutunately for most people I think the warranty was limited to 7 years and 70,000 miles. Which isn't a lot of miles for most people.
If you car isn't covered by the warranty there is a way to "reset" the speedometer.
You can turn the ignition slowly like you are going to start the engine. There is a very small "dead" space where you will see your guage lights go off.
What you want to do is cycle the ignition switch from off to that dead space. Each time you do it your stuck speedometer will move towards zero about 10 mph. So if its stuck on 40 you will have to cycle it at least 4 times.
At first you will probably actually hit the ignition and the engine will try to start.....just release it and try it again.
I know this because I have a 04 avalanche with 80,0000 miles and it has this problem about twice a month.

Replace the speed sensor, but also make sure you clear any codes, even if none are showing up, disconnect the battery for about 1 hour. After that drive it easy for a while, so it can relearn.
