Give us some more info on your car......auto/manual....type of driving....etc.

When's the last time you've done a tune-up. Plugs, wires, filters, fuel additive....etc.

It's an automatic i just recently bought it ( about 3 weeks ago ) havent had the money to do any type of tune up yet ( C.N.A class for the last 5 weeks ) and i only drove it for about a week before the alternator went out !!!!! As far as my driving style is concerned it is on the aggresive side. As everyone can tell i havent had much luck with the car so far but i know it will get better !!!!!! Again thanks for your replys

Well I'd start with the alternator......try taking it to auto parts store, have them test it, to see if it's bad. If it's bad, you'll prob just have to buy a new one.........as a side effect of the alternator, your battery may need have the chances to die later on.

Once you do that, then I'd do all the tune up stuff and then go from there.

I have already had the alternator checked and it does show bad currently i'm trying to fix the diode plate so that i don't have to replace the whole alternator 105 is the cheapest i found on a rebuilt one. BTW does anyone know where i can find a complete stainless steel exhaust system ??????????
