2 questions
1. when im in neutral slowing down from like 55-60, my headlights often 'blink' get real dim almost to the point of being off, then brighten up again, it does this a couple times until i stop. it also isnt consistent, seems to do it whenever it wants to
2. something inside my truck makes a 'whirr' sound, sounds electrical (like a bad ground in a radio someone told me) but it happens all the time, regardless of radio being on or not. it also increases with the rpms (like a turbo :p )

so if anyone has any suggestions or ideas as to what this might be it would be greatly appriciated... thanks in advance

:stupid: Sounds like your voltage is fluctuating at idle, which would most likely be a bad alternator. I think autozone will check it for free.
