2001 4x4 F-150 5.4L Triton. I have a P0352 error that refers to a bad COP on the #2 cyl. I have replaced the COP and plug, cleared the error but i still have the miss and the error returns. I have performed a test that was in the Haynes manual that says unplug all of the COP connectors and using a LED test light connect it to the + side and then check the harness connector negative side and have an assistance crank the engine.

When i do this on all other cyl. my test lamp flashes. When i do this on the #2 cyl the light stays lit does not flash. So there is power there however its not intermittent like it should be and the book refers to only it not flashing says nothing about it staying lit.

Any ideas what this indicates?

Thanks in advance for your help.

I have no clue but if you post in the 2001 era forums instead of the 1973-1979 forums you might get better results.

maybe this, i found this on the internet:

edit: I just looked at the Ford CD I have and it has all kinds of diagnostic info.

#3052 refers to the #2 cylinder.
#3053 is #3, 3056 is #6...etc.

edit: problem found and corrected. Pink/white wire at the coil pack connector was broke under the insulation. Took awhile to diagnose, figure out how to disassemble connector and solder everything up, but it now runs great. Back to terrorizing the locals.

Thanks in advance for your help.
