I have a 65 289 Mustang vert. I just finished up headers and put the plus wires back in and it runs like crap on maybe 4 cyl. I remember when i took the wires off they didnt seem to be in the correct order but failed to mark them, thinking "ill fix em the right way." Well i put them in as the book says and it has gone to poop. Any ideas why it would run better with the plus wires not in the factory order??? Help!!
