Hello everyone new here. My beloved 02 5.4 F150 has started to have some issues. Recenty drove it and it is missing in the lower <1000-<2000 RPM range. I pulled the codes P0305 #2 misfire, P0316 <1000 RPM. Any advice would be appreciated. I am assuming that it is the electronic control going out. Same thing happend in my wifes 01 GT. Would I be correct. Thanks for the help.

 

Its the COP going out and most people replace the plug too.
