To get my gauges accurate again, I literally spent all day pulling the needles off, putting them back on, and then reinstalling the gauges to see if they were right. I started with the tachometer, since I knew my car idled at about 700 RPM. I would put the needle on pointing below the zero line, then make a light mark with a pencil indicating where it was pointing to when I installed it. I would then reinstall the gauges, start my car, and see how close the idle was to 700. Depending on how close I was and which way I needed to go, I would remove the needle again and put it back on using the pencil mark I made earlier as a reference. When the tachometer was calibrated, I then adjusted the speedometer using the tachometer as a guide. (since I knew that in 5th gear, my car would do 60 MPH at 3000 RPM). I did the same procedure with the speedometer as with the tachometer, only this time I had to take a drive every time I wanted to see how close I was. The temperature and fuel gauge were pretty simple, it was mostly the tachometer and speedometer that sucked, especially the speedometer. Everything works fine now (my speedometer is 1 MPH fast) and I can assure you that I will never remove my needles again. And this is why I warn all of you as well to NEVER REMOVE YOUR NEEDLES
