i noticed tonight when my car (2000base) is just normally idleing that my headlights dim a bit. When i go to accelerate or push the gas down even in neutral that the lights get brighter. Do any of you all know what this could be from?

 

Do you have an underdriven alternator pulley?

 

could be the voltage regulator on ur alternator..... have a shop do a VAT-40/60 on it if ur more curious.....

if its the voltage regulator... ur gonna need to replace ur alternator.... cuz its inside it.... not seperate like the '60s 'n earlier....

 

first thing i'd check is the alternator (and the battery since it's easy to check).

def. check the tension of the alternator belt. could be the alternator pulley bearing too (inside the alt.)

 

i'm pretty shure its ur voltage regulator on ur alternator.... from what you said

if it is....

u have to replace the alternator....

then again.... do a VAT-40 to be shure.....
