service engine soon light
I have a 2000 ford f-150 with 4.6l. Service engine light went on today at first steady, wich made me think i had gotten some bad gas. While on interstate light began to flash so i took it to local part store that has hand held computer. Computer said nr 7 cylinder was not firing properly. Changed coil (not the best at newer vehicles) and plug. Light is still on and truck is still running very rough. Any ideas.

if youhave replaced the coil and plug then its probably a problem with your injector - try switching the injector with another cylinder and check your codes again. If the code if for the cylinder you put that injector in then you have a bed injector. I dont know how much those run but i would guess there not cheap
