OK I GOT CHEAP AND PUT SOME CHEAP GAS INTO MY MUSTANG AND NOW IT SRUNNIN FUNNY. IVE SINC GONE BACK TO PREMIUM BUT ITS STILL ACTIN GOOFY
THE ENGINE MAKES AWIERD SOUND THAT WASNT THERE BEFORE WHEN I ACCELERATE
AND THE IDLE JUST SOUNDS OFF, ANY SUGGESTIONS?

 

turn off caps lock

 

That won't help. Have you tried fuel injector cleaner or possibly changing your fuel filter?
