P0301 and P0306 codes
I started having a a loss of power yesterday on my 2000 F-150 XL with 4.6L engine. When I got home from work and hooked up the OBD tester to see what the probelm was I got a reading of P0301 and P0306 codes.
I tried some simple fixes like changing the fuel filter and cleaning air filter, but did not have any luck with fixing the problem.
I'm wondering what might be the next course of action? The truck is not making any noises or sputtering while running. It does vibrate more then usual while idling now and loses power while at highway speeds of 65mph or so.

i think 301 is failure of #1 cylinder ignition. 306 is failure of #6 cylinder ignition. DId you get the engine soaked with water in the last few days? if its not wet, then i would guess the spark plugs need changed out. second guess is the coils.

I didn't get the engine wet, but it we did have a really humid and wet night of rain here in Montana the night before it started acting up.
I'm going to check the plugs then the coils. The engine has about 55000 miles on it since it was rebuilt. So its gettting close to a needing the plugs changed anyway.
I'm hoping though that its not the fuel injectors. I'm not sure how often those things go out, but from what I've seen in my Haynes/Chilton books, it looks like a pain in the butt to change out injectors.

i dont know what you got for gasoline there in Montana. Here in Illinois all the gas is 10% ethanol. That cleans injectors and motors and very seldom have injector problems. I had a 89 F250 and drove 275k miles and NO injector problmes. Present F150 has over 185K and NO injector problems. stuff works.

We got a 85% for regular with no ehtnanol in it. Was definitely running better when I was in Arizona with 87% regular.
Whats the trick to removing the COP wires? Is the plug going into the COP or over the top of it. I was not able to see any tab or anything like that on it when I tried this evening.

there is a two pin connector that plugs into the CP. you have to pry on the little tab, then pull the two pin connector off. there is a 7 mm headed bolt holding the COP into the hole. remoe the screw, grap the COP and pull off the plug.

Well switched out the spark plugs on the cylinders that were giving me the error codes. The truck seems to running fine right now, but I probably need to change out the rest of the spark plugs too. It's getting really close to needing all of them changed.
Just got burned out doing the 2 though. Somehow I got a pebble down in the hole with the spark plug as I was trying to loosen it up and pull out. Spent somewhere between a hour or 2 trying to get the SOB out.
