I had just recently bought a scanner for my truck from autozone and pulled up some codes I originally had 351,359 and a 405 I fixed the 405 it was a tube on the EGR pipe but I don't understand what the 351 and 359 are about they're todo with ignition the little mannual that came with the the scanner It said ignition A and ignition I Maybe thats the reason I'm getting 9 miles to the gallon perhaps I have no clue Anybody have any clue cause I sure as hell dont any help is greatly appriciated thanks

 

SOrry I had forgot to mention what my application was it's a 1996 Ford Bronco XLT 5.8L automatic transmission sorry bout that totally slipped my mind
