Okay first time on here. Yup breaking down asking for help. Anyways I have a 98 f150. It started off with 5 misfires. So I did the basics...both coils, wires, plugs. Even went as far as injectors, o2 sensors, egr valve. Long story short im now down to 2 misfire. I've doubled checked everything and triple checked. I bought better wires and plugs after and still have the problem. Annoying, when I drive it surges when trying to maintain speed. Opinions?
