Im a bit confused with my car. It ran perfect till it started getting really cold this winter.It used to crank over with ease start right up.Now it barely cranks, it grunts just to start,then after you run it a while, shut it off, its ok.It will crank over alright, but then other times it will act if its straining to crank over. Ive tried 3 differant batteries, but still the same thing with each one.Im not sure if its the starter because I thought they would make a noise when going out, or if its the alt or voltage regulator. I just wanted to get your opinion, thanks.
