I have a 1995 Pontiac Bonneville, and for some reason when the temperature is very cold the dimmer switch wont work and will go to the lowest setting meaning at night you cant see any of your dashboard instruments, then when the temperature goes back up the dimmer switch starts working and all...
i own a 2000 pontiac bonneville ssei. i put regular fuel in it. but i hear it is recomended that you use premium fuel because of the supercharger. can anyone tell if this is true? and if so does it help on performance?
