I'm thinking I need a new alternator cause when I bought my car it made a lot of noise, and it's keeping up. It's doing what my last one did before it started to die, like when I brake the guage drops and the lights dim. It's taking longer to start up then it should too. So, when I look on the advance website they have two different versions for the 94's. They have a 140 amp and 124 amp version. I'm thinking I should get a 140 amp one since it would have more power. Any idea on if it matters?
