Brake light on with low pedal and Tachometer issue.
Just started my 1980 after sitting in the garage for 5 months. It's a 20,000 mile car. I decided to take it out and noticed the brake light came on with little pedal but still able to control the car to a stop. I returned home to notice the tachometer stuck at 5,000RPM. I turned the car on and off and did notice the needle would move but returned to 5,000RPM. Any help is always greatly appreciated.
