For no apparent reason, my Ford F-150 4.6 Triton engine started to miss. I hooked my diagnostic computer and received a code P0306 which indicated that the COP on cylinder 6 was missing.
As a test to see if the problem followed the COP, I swapped COP's 1 and 6, reset the computer and the truck ran OK, then started to miss.
I am still receiving a code P0306 with a different COP installed.
have the same problem?
