Hi and welcome to the forum

#7 COP (Coil On Plug) is the second from the back on the driver's side. It's also probably the hardest coil to replace on your engine
For some tips take a look at https://www.ford-trucks.com/forums/s...d.php?t=104027
Let us know how you make out with it.

 

thank you RACERGUY,your right its gonna be hard to reach,but telling me which one to replace makes a lot easier for me,i dont have to go one by one to know which one bad,i'm really glad i found this website by accident,i already ask all the closes ford dealer repair shop to my place but none of them willing to help and want me to pay tons of money just to diagnose and to replace the bad COP . THANK YOU FOR THE BIG HELP

 

You're welcome
Let us know if that cures it.

 

I have an 05 f150 and got the same code but says coil g .what one is that?

 

Welcome to the forum mstanton

The 7 in P0357 means #7 coil.
I haven't seen them listed by letters but G would be the 7th letter so that would make sense.

 

A=1
B=2

etc

P035x DTCs are often caused by the coil connector or harness as well as the COP itself.
