I've had this problem ever since I got my car. It's never really hurt anything, I'm just curious as to what could cause it. The main thing I've been noticing is on the computer display, sometimes some of the LEDs are out... like when it says "System Check OK" or whatever, part of the letters might be missing from what appears to be burned out parts of the led. But then sometimes when I turn on the car, they display is perfectly fine.
Also a few times I've been cruising at a decent speed with the music on, and I roll down my window and the stereo completely cuts off until the window finishes rolling down, when it comes back on again.
Could my car be hurting for electrical power, or what could cause this? I'm considering doing power pulleys sometime soon, and if this will lower the power even more.... could it cause problems?
Anyone had this happen before?
