Earlier I went to go pick up my take out and I tried to start my car and it started then slowly died down and I repeated this about 7 times and even tried to rev the engine and it reved then the car continued to slowly die down. The spark plugs are brand new as well as the alternator and idk I have to change the grommet (fuel filler) only but idk I cant think of what the problem could possibly be. Need advice, opinions. Thank you in advance!!!
