I replaced my battery after noticing a decent amount of corrosion on the + terminal and it was having a hard time turning over (was also 4 years old) since then I have this strange issue where sometimes, after driving it and it sitting for a while, the car wont start. It sunder like the starter so I had it replaced. I have a new battery and a starter now, and what happens......it sometimes just wont start, the gauge indicators shake and there is not power. If I leave it a for a few minutes and try, it will all of a sudden come to life after a few tries. I'm bewildered and have no idea where to go with this.....it's also impossible to recreate the problem in the shop. I had the battery tested and it was 100% charged.
