New plugs Big problems. wrong gap? wrong motorcraft plugs? codes and misfires
So my 03 ST has 70K miles and ran ok to i messed with it . it had original plugs and wires so i decided to put new ones in. I went with motorcraft because most people here said it was the safe way to go.
ordered plugs and they gave me AGSF22FM. Took the old ones out and they were AGSF22PM. does anyone know the difference between the two? did they give me the wrong plugs.
I pulled out the old plugs and the gap looked huge but i had no gauge to check them.
put the new ones in and it runs like crap. misfires and got 6 codes after drive it around. P0302, P0316, P0000, P0000, P0000, P0000.
from what i can tell P0000 is there is a problem but the computer is not sure what it is and the rest are miss fires. WHen i floor it and get high in the RPMS i get a blinking check engine light which from what i read means the engine is missing,
after everything was done i got my hands on some gap gauges and measured the old plugs and they measured .075. the truck calls for .052 to .056. i pulled the new plugs and they measured .047.
is the problem because my gap is two small?????
or i have the wrong plugs?? does the stock have the small electrode??? or is it just worn away????
or could it be something else. Its a lot of work to put everything out and regap them.
Here you can see the plugs. the new vs the old.
here is the diff plug numbers old is AGSF22PM the new is AGSF22FM
misfire on cyl 2
Misfire on start up
code P0000 all i cound find on this was that the computer has no idea what is going on
Help me
