1997 engine code says misfire
I have a 1997 F150 with a 4.6. I changed the plugs and wires, but get a engine code that says misfire cyl. 8. The coil is firing on the No. 8 position, but the truck still runs rough and the check engine light flashes from time to time while driving. Is there something else that could be giving me this code besides a misfire. Any info on this matter would be helpful.

I have a 97 4.6 also. changed the plugs and wires and coil packs. It drove good for a year and it started doing it again a couple weeks ago. Took it to A- Zone and #3 misfire. I got looking around and the clip to my #3 fuel injector had a broken clip. I tried to rig it. But it might need to be replaced. Also if you have a K@N filter it will clog up your MAFS, and possibly have the same problems.

I have a K&N air filter as well. What is a MAF??
Also, my truck shakes , more when accelerating and lightly when sitting still. Should I just a get a new air filter and what would you recommend?

Plus, the stuff in auto parts stores isn't very likely to have any measureable effect on the fuel system. Most fuels sold today have a very robust additive pack that makes most injector cleaners unneeded anyway.
