I don't think it's driveline related cuz I've replaced the guibo and drive shaft, and it happens even rolling along in neutral. It's not warped rotors cuz it happens when my foot is mashing the long skinny pedal, the little one on the left, the one in the middle, or even none at all. 1. buy a cd cleaner disc and clean the heads. After a long while, all of a sudden it will start working. Left channel comes in and out sometimes.
CDs sometimes stutter, especially in the beginning of a song.
Thanks a lot.
