Ok guys, I've checked my alternator and battery but both are good. When I start it and let it idle for a while it'll slowly die down then go off. I really need help before I end up spending money that could go into my alignment and brakes. On top of that I'm really getting tired of driving my grandparents' Cadi.

is the fuel pressure good?

Idle Air control valve? Try adjusting the set screw for the throttle blade a hair to get more air in. Not a permanent solution but should work for now if it's the issue.

Hows the Negative battery terminal?

Haven't gotten around to it yet, I'm more concerned about getting it out of a ghetto neighborhood and to my girl's dad's shop so we can start looking into it more. Is a bad tensioner possible? I've gone to Autozone to ask so they told it could possibly be that.

Why do you think it's electrical?

My GS300 does the same. But I figure its outta tune, and the fuel filter looks oem. So I need to try those first. It really hesitates when you hit the gas pedal and it doesn't throw power down till your at high speeds. I'm hoping it's not a compression problem like several others are having. Seems like it runs strong, just has something outta whack!

I forgot to mention my battery light comes on before it goes off, I was told it might be voltage regulator.

if it was the battery it wouldnt slowly go done it would just die....same go's with alternator....the battery light turns on because the car is shuting off...is your CEL on...

if your fuel is good then it has to do with air your getting eather not enogh or to much.....my car did some what the same thing but my CEL was on and i checked it and it was my MAF sensor.....im not saying its the same prob as yours but you have to trouble shoot the prob....

Alright I will give it all a try, hopefully I get it running tonight since it's stuck at my buddy's house and my girl's dad is the only one with a trailer to haul it out.

Ok someone told me it's most likely the alternator since Autozone's tester lies.
