when problem started, car would sometimes lose power and idle down when stopped, once stopped wouldn't start back up until
cooled down. Oil and spark plugs changed. Now hard starting. once started,shuts down after a few minutes; gas gauge fluctuating. Husband thinks its the fuel filler flap or fuel pump relay switch. Help!

when problem started, car would sometimes lose power & idle down when stopped; once stopped wouldnt start back up until cooled down. oil & spark plugs changed. now hard starting & shuts down few minutes after starting. gas gauge fluctuating. husband thinks it's either the fuel filler flap (sticking) or fuel pump relay switch (bad). any ideas?

check the MAS (MASS AIR FLOW ) , maybe bad.

How's the frequency like? Every drive?

Do you have hunting idle? revs up and down by itself?

Thanks
