I have many problems...
1) While driving my battery voltage is always up and down. It is causeing my car to have different rpm at each stop. When i press the back window defogger, The battery voltage drops to 12.3-8. Normally it would be at 13.8. I don't know what it is?
2) When i was driving this morning and downshifted to pass this semi, after i passed the semi I shifted to neutral to let it roll because there was a car not so far ahead. Then the car's idle went to all the way down and the car died. Wehn i drive normally the idle usaully drops to only 800prm or 900rpm.
3) My autometer boost gauge shows that my car has different vaccum sometime. I mean sometimes it could be at 20 and then 15 and the 22 and so on.
Please give help insights and advice. thanks.
