Can I get an answer besides...
...hit the reset button?
This afternoon/evening I got into my '94 LS to go for a short ride. When I started the car, I noticed the Maintenance Required light is on constant now. I have no clue why. I just had the oil changed, along with the spark plugs. Other than taking a while to "warm-up" in the morning, there is really nothing wrong with the car. Any ideas are greatly appreciated.
