P0353 help

Hey all! Ive got misfire and stutter on my 04 5.4L and throwing P0353. I have checked for chafing around accumulator, chanced out the COP connector, zip tied all wires away from the accumulator, swapped out COP. Is the next step untaping the wire harness and following it back to the PCM to check for damage? I found an article on testing the wire and conection with a voltmeter but I didnt understand the termenology. Any suggestions would be greatly appreciated.
