p0300 code
Ok so i have a 5.4 2006 xlt, i have 120k on the motor. I had new plugs put in(no plugs cracked), and i did the coils. After the work was done p0300 came up i put new coils in angain, cleaned the air filter(amsoil dry filter), and i replaced my fuel filter about 30,000 miles ago. Should i pull all the plugs and put new ones in.
Any ideas on how to fix this?
Thanks yall

Yep, -PO300 "Random Misfire" just informs the tech to mode 6 it, - the info is recorded in cylinder history. Does us absolutely no good, we don't have that $10,000 diagnostic equipment to read it's mind...
I'd push the engine until the CEL blinks 5 or 6 times. Once that happens, do this one more time, - maybe the scanner will give you better direction once that's been achieved. It's worked in the past.
Otherwise, it's off to the dealership.

X2.. I wouldnt use Champion plugs myself in my lawnmower.. I would still get it to give up the code. It will eventually. Try going up a hill slowly that might do it put a load on the engine..

Crap! That's right, - I'm mistaken, that's for a 2 valve not the 3 valve. Thought the OP had a pre 04 model 2 valve for some reason.
The Champions can cause headaches in the 3V as well. There you better off with the Motorcrafts IMO.
