my battery died and i had i jumped but ive been having to jump start it to start the car every time i want to start the car
Expert:  Chad Farhat replied 2 months ago.

if you keep wanting to start it each time , tells me battery no good

you have to check battery or if no volt meter available then trying replacing battery , you have to start here .

if alternator is good and battery no good it will start and die .

make sure the big breather hose to throttle body , is on correct and no hole in it , creating a vacuum leak.

okay I know my breather hose shredded when I pulled it off to start changing the alternator and I used hose repair tape on it but the engine just stalls out again
