Why does my car say check gages?
Grand Prix gtp 1998. So this morning I turn the car
on. Lights and dash come on. I turn to start it.
Power goes off like a bad battery. A second later
lights come back on. And I turn the ignition and
this time the car starts right up. Idk if it’s the
alternator because last week i replaced a bad
terminal screw cause it kept disconnecting from the
battery. While doing this I tested the alternator by
having the car run and unplugging the battery. It still
ran. So it’s night now. And on the HUD display it
says check Gages I have about a half tank of gas.
My
Oils index is at 35%. What should I do.
